Noise Absorption within Houses of Worship
Why is it so important to use professionals when dealing with with noise control & reverberation problems within Houses of Worship?
This type of acoustic need requires 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 allows for significant reverberation, also known as echos. Reverberation can reduce the speech legibility and can make otherwise good church sound systems sound awkard. The complex nature of noise control and acoustical solutions for these problems require expert knowledge which All Noise Control has.
There is a difference between noise control or sound control and 'church acoustics'. Simply absorbing excess sound, as done in many commercial and industrial applications, is not the best approach for church acoustics. Noise control solutions ideally need to be configured by professional noise control specialists to balance noise absorption, noise reflection, noise barrier products and to deliver them in an aesthetically pleasing result.
How Sound and Hearing Come to Be...
To help better understand, sounds are vibrations translated by your ear the effect is the sensation of hearing. These vibrations ( sound waves ) are actually heat. When multiple lengths of these waves cross, or sound waves hit reflective matter, loss of quality, reverberation and "noise" occurs.
What is noise?
Any unwanted sound is perceived as a noise. The term is definitely subjective, since what is music for one person can very well be noise for another. When such unwanted sounds are excessive, their effects can be destructive, which is now known by the name of noise pollution. Adverse noise effects fall into three categories, physiological, psychological and communicational. Unfortunately, there aren't any known and adopted remedies for the last two categories. Noise pollution is a complex problem and surveys show a disturbing fact, that noise levels are continually rising in cities. Perhaps one of many reasons to focus on the sounds within other aspects of our lifes like home, worship buildings and work.
Are there many different types of noise?
As far as the sounds inside buildings go, we can speak about two main ways of transmission: Mechanical Noise and Human Activity Noise. Sound emanated from either human activity or mechanical noise inside the building travels airborne through walls, ceiling or floor.
Sounds from human activity can include loud voice, foot steps, activity like moving things, office busy work or voice through amplified systems.
Mechanical noise refers to the sounds produced by elevators, generators, air conditioning systems and so on. Secondly, interior sound can be transmitted not only travel through air, but through the building itself. The former is easier to abate than the latter through wall or ceiling assemblies which meet certain established performance standards.
Dealing with sound...
There is no one size fits all for church acoustics especially as the churches are communal places that act as mutlipurpose spaces for large gatherings and events as well as venues for smaller groups and classroom activities.
Many contractors installing these systems may not realize that reverberation time ideal for music can make the spoken word difficult to understand. The structural differences of these spaces( cathedrals, class rooms, multi-purpose, private rooms) and their contents make custom acoustic solutions for your project necessary, not to mention the aesthetics in the typical House of Worship. The materials, volume of space, variety of speech and sounds are all contributing factors in making a positive experience with improved interest, attention spans and even less fatigue. When all the types of noises, building surfaces and understanding of all mitigating factors are observed and understood the end result will be harmoniuous.
Noise control assessments by our specialists will help:
- Identify noise sources & workplace noise hazards
- Evaluate noise levels compared to levels within regulation/li>
- Evaluate and improve any existing noise control measures in place/li>
Once All Noise Control determines and identifies all the issues unique to your environment, we will design and install a noise control solution which will be proven to reduce, and in some cases stop, the noise irritant issues.
