Soundproofing Examples
Example 1.
Reflected sounds bouncing off hard surfaces increase noise levels
A great example of how reflected sounds bouncing off hard surfaces can greatly increase noise levels in an enclosed environment is illustrated in the drawing below. We will call it the “Lawn Mower Experience”.
The man who is doing the mowing is untroubled by the noise of the lawn mower for two reasons, firstly he is wearing sound absorbing acoustic foam hearing protection, and secondly, he is only exposed to the direct sound of the engine. He is not exposed to any sound waves being reflected back towards him.
The people who are sitting on the porch are having a terrible time for three reasons. First of all, they are not wearing hearing protection, secondly they are exposed to the direct sound of the mower, and thirdly, they are being subjected to the reflected sounds of the mower bouncing off the wall behind them and also from the ceiling above them. It is the noise being reflected off the ceiling and wall behind them that makes it impossible for them to sit outside happily reading the paper while the lawn is being mowed.
Installing soundproof acoustic insulation on the wall behind where they are sitting or on the ceiling would be one way of decreasing the noise level they are experiencing.
Example 2
Sound reflections. Lawn mowers should Never be started inside a shed!
Why is it that most people instinctively know never to start or shut down the lawn mower inside the garage or garden shed?
The most likely answer to this question is that at sometime in the distance past some of us did start or shut down the lawn mower in an enclosed environment and quickly realized that the noise level was overpowering and we most likely hurt our ears.
Starting a mower outside is preferable because there are no reflected sound waves from the engine. Running the engine in an enclosed space like a garage or shed means all the noise from the engine is reflected off the floor, ceiling and walls and simply overpowers the user. This is often a lesson people experience only once.
It would be possible to start a mower in the shed if all the walls and ceiling were covered in acoustic foam panels. These sound absorbing panels would soak up all the reflections and the user would only hear the direct sound of the engine.
Example 3
Restaurants | Cafes, Classrooms, Offices | Call Centers, Gymnasiums and Residential Buildings can all Suffer from Echoes and Excessive Noise.
Soundproofing acoustic ceiling panels and sound proofing acoustic foam panels are ideal sound insulation solutions for noise problems in modern residential buildings, restaurants, cafes, offices, call centers and gymnasiums, which can all suffer from a build up of unwanted noise when rooms becomes busy.
Installing acoustic foam in the form a acoustic ceiling panels and/or acoustic walls panels can soundproof these rooms from echoes, long reverberation times and will remove unwanted noise. Sound insulation materials will absorb the sound energy that is being reflected of the hard surfaces such as windows, wooden floors and hard bench tops. Sound insulation in the form a of acoustic ceiling panels and acoustic wall panels are the most cost effective way to soundproof a room and make it quieter.
Most unwanted noise generated in these rooms is generally in the frequency range of 250 - 5000 Hz. Sound deadening acoustic foam ceiling tiles and acoustic foam panels are ideal at absorbing sound energy in the 250 - 5000 Hz range.
