Sound Blocking Vs Sound Absorption – The Difference Will Make or Break Your Soundproofing Experience

Sound Blocking Vs Sound Absorption – The Difference Will Make or Break Your Soundproofing Experience

Anybody having the experience of having been exposed to uncontrolled or unwanted sound in an apartment, home, school, theater or business environment will be aware how irritating it can become. Also, unrestrained sound can be more than just be irritating to your nerves; certain type of noises can really injure your hearing ability.

High-frequency and high-intensity sounds, are the most harmful to the ears because the number and intensity of the waves of sound that are being transmitted are very high. Even a little change in the level of decibels has a substantial effect on the way you perceive the sound; a variation of even 3 decibels is important. An increase of just 10 decibels in fact makes a sound appear two times as loud to our ear—an increase of  100-percent.

What can you do to regulate sound?

Choosing from the numerous products for sound-control available on the market isn’t going to be easy but an examination of the products, will reveal to you that they’re mainly divided into two clear categories: sound blocking and absorption.

Sound blocking

Sound blocking consists of preventing sound waves from getting into places where they are not welcome. For example, your neighbors playing continuous music or the incessant noise of traffic coming from the highway close by may be enough to tire you. To block similar sounds from traversing through ceilings, walls, and floors, you have to add MASS, which usually means constructing thicker walls and ceilings and suspended floors with denser materials.

Sound absorption

Sound absorption, as indicated by the term, encompasses the use of the specific material for absorbing the sound waves and stop them from bringing about distortion like reverberation or echoes. Suppose a room is big and empty it cannot offer hardly any sound absorption, as the room has no objects in it to prevent the sound waves from bouncing off the naked walls. But once you add carpet, heavy drapes and some upholstered furniture, you’ll immediately become aware of some improvement. If the objects in the room are more fibrous they can absorb sound better. This would suggest that strengthening the decorative materials in the room with some extra acoustical products like panels or other products particularly designed for absorbing sound will help to improve the environment of sound even more.

As can be understood from the above descriptions, soundproofing is a not such an easy process, but involves some complications. Sounds produced by various sources have different frequencies and the levels of energy produced by them are also different and therefore each of them have to be treated accordingly in slightly different ways using different techniques.
