Acoustics deals with the study of sound

In the heart if Texas, Milan middle school had a noise reverberation problem typical to institution spaces such as gyms, cafeterias, auditorium and general purpose rooms. We all associate the echoes, noise and reverberation of sound with gyms, pool areas & large auditorium / multipurpose rooms and certainly can relate to the high noise levels in these types of rooms. In this middle school gymnasium (a problem in virtual all gymnasiums), the sound bounces off the walls more than the basketballs. Due to the volume and space in these rooms and lack of noise absorbents, the noise grows and creates echoes and reverberation seriously impeding speech intelligibility. When the gym was in use, the conversation next to you was indistinguishable from the conversation across the floor.

Theta Pro2Serve Management Company
Theta Pro2Serve Management Company Contacted All Noise Control to provide them with ceiling tiles for their existing drop in ceilings. After receiving the sizes and dimensions, All Noise Control provided a solution using ANC-1010 1 this Fiberglass ceiling tiles 2mil. White pebble grain facing.

Guide to Sound Isolation and Noise Control
It starts with a simple question, “How can I stop noise from going through this wall?” We have the answer, and it usually involves patching noise leaks in the floor, ceiling joists, windows, and vibrating structures that carry sound waves through solid material.

4 ways to achieve effective noise reduction:
Sound Insulation. With this approach to noise control, the goal is to introduce a solid barrier to the environment that helps lessen the reverberation of the sound waves. Much like the insulation of a house helps keeps warm air in and cold air out (and vice versa depending on the seasons), this approach effectively mitigates the transference of sound within a defined area by adding materials which block the transfer of sound waves. High-density materials such as concrete, steel, and stone are often used in this application because of they are difficult to penetrate.

All Noise Control manufactures heavy duty, weather resistant Sound Curtains for outdoor applications. We offer modular panels that can be used for short-term or temporary applications such as construction sites or drilling operations as well as long-term permanent applications such as HVAC systems, dust collectors and generators.

Sound is propagated in air, much like blowing up a large balloon, which expands equally in all directions.
For sound to be generated and heard it must have a source, a medium through which to pass and a receiver.

The loudest sound in recorded history occurred on August 27, 1883, just off the coast of Jakarta, Indonesia.
A volcano on the small island of Krakatoa was undergoing the cataclysmic stage of its months-long eruption. At 10:20 AM the volcano exploded with a sound heard, literally, around the world.

Noise Absorption and Acoustic Problems with Noise within Houses of Worship
Houses of Worship acoustics require special attention and knowledge to the nuances of voluminous spaces, hard surfaces, especially in the new architectural designs of today’s buildings. This excessive space is wonderfully impressive but allows for significant reverberation, which we are familiar with as echoes. Reverberation can reduce speech legibility and can make otherwise good church sound systems sound awkward. Imagine your ear being bombarded with an array of sounds at different decibels repeatedly served in waves. These sound waves maintain a surprising amount of energy and continue on absorbing and interfering with other sound waves.
