Noise is considered a serious threat to the environmental health. Some of the adverse effects of noise pollution are given below:

  1. It interferes with speech. In the presence of noise we may not able to follow, what the other person is saying.
  2. Noise leads to emotional and behavioral stress. A person may feel disturbed in the presence of loud noise such as produced by heating of drums.
  3. Noise may permanently damage hearing. A sudden loud noise can cause severe damage to the eardrum.
  4. Noise increases the chances of occurrence of diseases such as headache, blood pressure, heart failure, etc.
  5. Noise leads to increased heart beat, constriction of blood vessels and dilation of pupil.
  6. Noise is a problem especially for patients who need rest.
  7. Noise may cause damage to liver, brain and heart.

Noise pollution describes any sound created by people, animals, and machines that disturbs the environment. With these noise pollution facts, you can better understand its causes, health risks, and protection techniques.

We master noise, we do provide end to end solutions, in residential noise, industrial noise, outdoor noise, vehicular noise pollutions, sound pollution, unwanted sound, noise isolation’s, Vibration control, & white noise control solutions.

Worship Perfections by Apocalypse

In churches, synagogues and worship centers large or small, words and music can sound incomprehensible to the congregation if sound is not properly controlled.

  • Poor sound quality is common in churches because of an abundance of hard surface materials. Brick, marble, stone, tile, glass, wood and sheet rock are all acoustically reflective.
  • Sound waves bounce back and forth between parallel surfaces, creating a confusion of noise until they finally decay. Even the most strategically-placed speakers and microphones will not compensate for poor acoustics.
    Every room needs some absorptive materials and some reflective materials to get the right acoustic mix for the room’s intended purpose. The challenge is to find that balance.
  • Apocalypse Acoustics Wall Panels and Acoustic Panels from Acube acoustic inc. are designed to absorb airborne sound energy and reduce a room’s overall noise, reverberation and standing waves—creating interiors that reduce the din without sacrificing the divine.

Live Sound Engineering…Part 1

The basics of live sound mixing with an emphasis on non-technical details, and oriented towards acoustic music settings.

  • It is based upon my experiences with sound at different places, Installations and a few other venues over the past 13 year.
  1. The definitive Goals of Live Sound Mixing
  • Do what the artist wants. Not what YOU want.
  • Get the best sound in the hall you can with the equipment available. Don’t Dream for what U cant Get….in the Hall.
  • As a subsidiary to these, you are typically a consultant to the venue (or the artist if you are traveling with them) regarding the appropriate equipment necessary for providing a quality aural experience for the audience.
  • This means, if you are engineer for a venue, carefully reading the sound riders for a visiting artist, being certain that you will have the equipment requested available or, if not, being certain that the artist has approved whatever modifications you suggest.
  • If you are traveling sound engineer for an artist, this means making certain that a complete, detailed sound rider is made available to all venues well before the performance, and making yourself available to discuss these with a representative of the venue.
  • At the Venue…..
  • Start Up Technically, Following the Signal
  • Proceeding with following the audio signal from the artist through the various wires and equipment until it reaches the speakers.
  • This is the usual procedure to apply whenever there is some problem with the system that you don’t know the cause for – follow the signal, carefully checking each lead, plug and piece of equipment until you isolate the problem. A bit of background definitions and equations will be given in the first section, but these really gloss over a lot of the details, so see the references for more on this.

Next Post Ill be covering How to measure Signals, Microphones &other Inputs, Mixer & Mixing….So on and On and on….

  • Diffusors are used to reduce or eliminate repetitive echoes that occur in rooms/halls having parallel walls and a flat ceiling. Although there are different philosophies about how much natural reverberation recording studios and listening rooms should have, all professional studio designers agree that periodic reflections caused by parallel walls are best avoided.
  • Therefore, diffusion is often used in addition to absorption to tame these reflections. Such treatment is universally accepted as better than making the room completely dead by covering all of the walls with absorbent material.
  • For me, the ideal listening room has a mix of reflective and absorptive surfaces, with no one large area all live or all dead sounding. Understand that “live” and “dead” as described here concern only the mid and upper frequencies. Low frequency treatment is another matter entirely, and will be described separately. #Acoustics, #Audio, #Sound, #Noise, #Roomacoustics, #Diffusers, #absorbers.

Fundamentals of Room Acoustics

Most #sound #reinforcement #systems are located indoors, and the acoustical properties of the enclosed space have a profound effect on the system’s requirements and its performance.

Our study begins with a #discussion of #sound #absorption and #reflection, the growth and decay of #sound fields in a room, #reverberation, direct and reverberant sound fields, critical distance, and room constant.

If analyzed in detail, any enclosed space is quite complex acoustically.
