Today with Open Plan Spaces being the first choice, the importance of good acoustics and noise reduction in an office environment is the need of the hour right now and is growing up. Today, we are surrounded by sound at all times. Some sounds are pleasant and soothing; others are very very annoying and distracting which are the true factors behind our physical or psychological diseases, illness, or malfunctions.

Sound affects the way we feel and behave, and especially in our working environment, sound is particularly critical and very influential on our performance.

Complaints in the office often involve the lack of speech privacy, high noise levels and the distraction of, overheard extraneous conversations. These complaints risk becoming more pronounced when traditional office walls are replaced by partial height panels, which allow sound to circulate more freely throughout a space.

CASE STUDY: T HUB: T-Hub is the heart of the Telangana startup and technology ecosystem.

Web Link

T-Hub is a unique public/private partnership between the government of Telangana, 3 of India’s premier academic institutes (IIIT-H, ISB & NALSAR) and key private sector leaders. It stands at the intersection of the start-up, academic, corporate, research and government sectors.

T-Hub is designed for technology-related start-ups, and its mission is to catalyse the creation of one of the tightest and most vibrant entrepreneur communities in the world in order to encourage and fuel more start-up success stories in India.

The entire Hyderabad startup ecosystem with a state-of-the-art 70,000 square foot building called CatalysT, the largest building in India to be entirely dedicated to entrepreneurship. Located at the IIIT-H Campus, gachibowli, the sprawling building will bring the start-up community together by providing a platform for entrepreneurs, mentors, investors and academia to interact and collaborate.

The world-class infrastructure facilities at the building will be used for co-working spaces, meetings, mentoring, networking sessions and conferences. By giving access to top mentors, investors and academia, the T-Hub building will help every entrepreneur realize their dream; it’s the first open office space design, harnessing the green revolution technology.

Putting the Pieces Together-Technical annotates

In an open plan office, the STC (Sound Transmission Class) and NRC (Noise Reduction Coefficient) must be balanced to achieve good speech privacy, while background sound levels are comfortably maintained. The combination and interaction of the STC and NRC is measured as the Noise Isolation Class (NIC).

Actually a furniture system with a NIC of 21 will reduce sound by approximately 21 decibels between work stations. (This looks completely new to us). Developed in the 1970’s, this criteria has fallen into somewhat of non-use; probably though lack of understanding of it by those who should like the (Architects, Interior Designers and some amateur Carpenters) be using it in the design and evaluation of space have totally ignored it. (No Problem we can still can handle this ignorance)

Each component in the open plan can be tested under these criteria; however, an educated evaluation of traditional properties (NRC, STC, etc.) can suffice. (We will require that at a later stage)

It is important to recognize that all of the components in an open plan office – ceiling, walls, floor and partitions, don’t forget the HVAC and mechanical systems – contribute to or detract from the overall acoustical performance of the space, but today designers just tend to forget this balancing act, their focus remains only of the designing and the aesthetics of the office

Each component can only compensate so much for the poor performance of another component. When too many compromises are made, the overall performance suffers. “NO ONE COMPONENT CAN DO THE JOB. IT CAN ONLY DO ITS JOB!”

We must first understand the Performance criteria for open plan offices which must include:

  • Ceilings NRC .75 or higher
  • Partitions STC 21 or higher
  • Partitions NRC .70 or higher
  • Walls NRC .80 or higher
  • Floor (Carpeted) NRC .15

This basic understanding of sound, its measurement, and how to control it will help us to create the most functional acoustical environment in open plan and other office space.

Why Silence Is So Good For Your Brain

In a loud and distracting world, finding pockets of stillness can benefit your brain and body. Here are four science-backed reasons why.

We live in a loud and distracting world, where silence is increasingly difficult to come by — and that may be negatively affecting our health.

In fact, a 2011 World Health Organization report called noise pollution a “modern plague,” concluding that “there is overwhelming evidence that exposure to environmental noise has adverse effects on the health of the population.”

We’re constantly filling our ears with music, TV and radio news, podcasts and, of course, the multitude of sounds that we create nonstop in our own heads. Think about it: How many moments each day do you spend in total silence? The answer is probably very few.

As our internal and external environments become louder and louder, more people are beginning to seek out silence, whether through a practice of sitting quietly for 10 minutes every morning or heading off to a 10-day silent retreat.

Inspired to go find some peace and quiet? Here are four science-backed ways that silence is good for your brain — and how making time for it can make you feel less stressed, more focused and more creative.

  1. Silence relieves stress and tension. 

Florence Nightingale, the 19th century British nurse and social activist, once wrote that “Unnecessary noise is the most cruel absence of care that can be inflicted on sick or well.” Nightgale argued that needless sounds could cause distress, sleep loss and alarm for recovering patients.

It turns out that noise pollution has been found to lead to high blood pressure and heart attacks, as well as impairing hearing and overall health. Loud noises raise stress levels by activating the brain’s amygdala and causing the release of the stress hormone cortisol, according to research.

An unpublished 2004 paper by environmental psychologist Dr. Craig Zimring suggests that higher noise levels in neonatal intensive care units led to elevated blood pressure, increased heart rates and disrupted patient sleep patterns.

Just as too much noise can cause stress and tension, research has found that silence has the opposite effect, releasing tension in the brain and body.

A 2006 study published in the journal Heart found two minutes of silence to be more relaxing than listening to “relaxing” music, based on changes in blood pressure and blood circulation in the brain.

  1. Silence replenishes our mental resources.

In our everyday lives, sensory input is being thrown at us from every angle. When we can finally get away from these sonic disruptions, our brains’ attention centers have the opportunity to restore themselves.

The ceaseless attentional demands of modern life put a significant burden on the prefrontal cortex of the brain, which is involved in high-order thinking, decision-making and problem-solving.

As a result, our attentional resources become drained. When those attention resources are depleted, we become distracted and mentally fatigued, and may struggle to focus, solve problems and come up with new ideas.

But according to attention restoration theory, the brain can restore its finite cognitive resources when we’re in environments with lower levels of sensory input than usual. In silence — for instance, the quiet stillness you find when walking alone in nature — the brain can let down its sensory guard, so to speak.

  1. In silence, we can tap into the brain’s default mode network. 

The default mode network of the brain is activated when we engage in what scientists refer to as “self-generated cognition,” such as daydreaming, meditating, fantasizing about the future or just letting our minds wander.

When the brain is idle and disengaged from external stimuli, we can finally tap into our inner stream of thoughts, emotions, memories and ideas. Engaging this network helps us to make meaning out of our experiences, empathize with others, be more creative and reflect on our own mental and emotional states.

In order to do this, it’s necessary to break away from the distractions that keep us lingering on the shallow surfaces of the mind. Silence is one way of getting there.

Default mode activity helps us think deeply and creatively. As Herman Melville once wrote, “All profound things and emotions of things are preceded and attended by silence.”

  1. Getting quiet can regenerate brain cells.

Silence can quite literally grow the brain.

A 2013 study on mice, published in the journal Brain, Structure, and Function, involved comparing the effects of ambient noise, white noise, pup calls and silence on the rodents’ brains. Although the researchers intended to use silence as a control in the study, they found that two hours of silence daily led to the development of new cells in the hippocampus, a key brain region associated with learning, memory and emotion.

While preliminary, the findings suggested that silence could be therapeutic for conditions like depression and Alzheimer’s, which are associated with decreased rates of neuron regeneration in the hippocampus.

What is Reverberation by Apocalypse Part 2

What is Reverberation? Part Two (Continued from Part One)

You can say,

  • What on earth is reverberation time?
  • How do I treat it.?
  • In a room with high absorption or with few reflections the sound dies immediately or very quickly allowing us to reply.
  • Well what is the time taken for noise to stop after the noise source has ceased, is it measured in milliseconds”

With a relatively dead room (a room with a short reverberation time) the noise (words) created by the spoken sentence become inaudible relatively quickly, allowing the response to be heard and a further question asked, with relatively ease.

However in a live room (a room with a higher reverberation time) this becomes a much more difficult task to carry out. The sound of the previous word over laps the sound of the next word and the sound of the first sentence over laps the sounds within the second sentence and so on and so forth. This means the examples from above would sound more like. (Where capital words express more clearly heard word)


How do i TREAT it? the time for NOISE to Stop…… You get the idea.

It is like having a conversation in a round, like when you sang nursery songs as a child.

However high reverberation time isn’t always a bad thing, if you are Gregorian monk or in a vocal group, a longer reverberation time is desired as it produces a more appealing and warm sound.

This provides a much desired atmosphere to listen or to record in. Producing music in a dead room for this type of activity would really take away from the atmosphere and kill the mood and ambiance trying to be achieved, as the notes world die very quickly and make the sound appear very flat.

As we all know reverberation itself is a perplexed subject which needs more elaborative, more amplified refinement which we can establish and Institute for your complex issues.

What is Reverberation by Apocalypse Part 1

What is Reverberation???

Reverberation is another name for what most people know and understand as echo. The following analogy explains what reverberation is quite concisely without getting overly technical.

If you press the accelerator pedal of a car, the car accelerates to a certain speed. If the road is smooth and level the speed will remain constant. With a constant force on the accelerator, the engine produces enough horse power to overcome frictional and aerodynamic losses and maintain a steady and even speed, or steady state condition. If you take your foot of the off the accelerator, the car will gradually slow, and come to a stop.

Sound within a room acts similarly to this. When a loudspeaker is turned, it emits noise into the room that quickly grows to a certain level. This level is the steady state or equilibrium point at which the sound energy radiated from the loudspeaker is enough to over come loses in the air and at the room boundaries.

A greater sound energy radiated from the loudspeaker will result in a higher equilibrium level, whereas less energy to the loudspeaker will result in a lower equilibrium level. If you push your foot flat to the floor in the car the equilibrium or speed will be much faster, than those Sunday drivers who only slightly depress the accelerator pedal.

When the loudspeaker is turned off, it takes a finite length of time for the sound level in the room to decay to inaudibility. This means there is an exact amount of time from when the loudspeaker is turned off until the sound from the speaker cannot be heard.

For most environments such as conference rooms, classrooms, sports halls, offices and the typical working environment or public space, the longer the time between the noise source stopping and the noise becoming inaudible, the worse the acoustic environment is perceived. This is because a lot of words and noises overlap one an another.

You can say, ” What on earth is reverberation time? How do I treat it.?

Provision for children having special hearing or communication needs

For the purposes of this document, special hearing or communication needs include, but are not limited to, children with permanent hearing impairment; or with severe or complex needs including:

  • speech, language and communication difficulties;
  • visual impairments;
  • fluctuating hearing impairments caused by conductive hearing loss;
  • attention deficit hyperactivity disorders (ADHD);
  • an auditory processing disorder or difficulty;
  • being on the autistic spectrum.

The Equality Act 2010 places a duty on all schools and Local Authorities to prepare and implement accessibility strategies and plans to increase over time the accessibility of schools for disabled pupils and staff. Schools and Local Authorities are required to provide strategies for:

  1. increasing the extent to which disabled pupils can participate in a school’s curriculum.
  2. improving the physical environment of schools for the purpose of increasing the extent to which disabled pupils are able to take advantage of education and the benefits, facilities and services provided.
  3. improving the delivery to disabled pupils of information that is readily accessible to pupils who are not disabled.

This could mean provision of physical aids and acoustic improvements and aids. These will often benefit both hearing-impaired and other pupils.

When alterations affect the acoustics of a space then improvement of the acoustics to promote better access for children with special needs, including hearing impairments, must be considered.

Approved Document M: 2004 – Access to and use of buildings, in support of the Building Regulations includes requirements for access for children with special needs.

New-build, conversion and refurbishment work performance Standards.

NEW BUILDING-CONVERSION And REFURBISHMENT: Performance Standards for Acoustics.

The School Premises Regulations and the Independent School Standards apply to refurbishment work, and the acoustic standards for refurbishment works given in this document apply. Where there is a need to upgrade the acoustic performance of an existing building or when refurbishment is undertaken for other reasons, then the building should meet, as far as reasonably practicable, the acoustic performance given in these guidelines to satisfy the School Premises Regulations, the Independent School Standards and the Equality Act.

Although Building Regulations do not apply to all alteration and refurbishment work, it is desirable that such work should consider acoustics and incorporate upgrading of the acoustics as appropriate. In the case of existing buildings, Part E of the Building Regulations applies to material changes of use as defined in Building Regulations. The Tables give values for both new buildings in the columns labelled “new build” and for new elements of a refurbishment in the columns labelled “refurbishment”.

Where there is a material change of use as defined in the Building Regulations, such work shall be carried out as is necessary to ensure that the building complies with the applicable requirements of Requirement E4 of the Building Regulations. In these cases, the ‘refurbishment’ criteria contained within this document apply. The School Premises Regulations and Independent School Standards apply whether or not there is a material change of use.

SOUNDPROOFING BY APOCALYPSE ACOUSTICS: Soundproofing is any means of reducing the sound pressure with respect to a specified sound source and receptor. There are several basic approaches to reducing sound: increasing the distance between source and receiver, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles, or using active anti noise sound generators. TWO DISTINCT SOUNDPROOFING Problems:

  • Two distinct soundproofing problems may need to be considered when designing acoustic treatments – to improve the sound within a room (See anechoic chamber), and reduce sound leakage to/from adjacent rooms or outdoors.
  • Acoustic quieting, noise mitigation, and noise control can be used to limit unwanted noise.
  • Soundproofing can suppress unwanted indirect sound waves such as reflections that cause echoes and resonances that cause reverberation.
  • Soundproofing can reduce the transmission of unwanted direct sound waves from the source to an involuntary listener through the use of distance and intervening objects in the sound path.
