Engineering noise control 259 elastomeric materials such as rubber are often preferred over steel springs because their greater damping reduces the large vibration amplitudes which occur when an excitation frequency coincides with the isolation system resonance (see Figure 10.14).See all results for this questionsp.info How are immission and emission values used in noise control?Normally the noise control program will be started using as a basis A-weighted immission or noise exposure levels for which the standard ISO 11690-1 recommends target values and the principles of noise control planning. A more precise way is to use immission and emission values in frequency bands as follows.See all results for this questionsp.info Which is the most effective noise reduction method?Structural separation is one of the most effective noise reduction methods. Walls with staggered studs or double stud construction are most effective.

Here’s the deal, absorbing sound and blocking sound are two totally different things. Sound absorbers prevent sound from continuing to bounce and echo through out a space. This is done by disrupting the sounds path and converting the energy to heat. This is often done by using fluffy and porous materials. Blocking sound requires materials that are heavy, dense and thick. These materials are often used in multi-layered assem…See more on acousticalsolutions.comsp.info SOUND TRANSMISSION CLASS RATINGS FOR CONCRETE …DETERMINING SOUND TRANSMISSION CLASS (STC) FOR CONCRETE MASONRY.
