|Debunking Bogus Underlayment Ratings|
Starting first with the characteristics of a soundproof Flooring underlay suited for isolating impact footfall noise. Resilience is key to isolating impact footfall noise as it allows a cushion for the energy of sound pressure of a footstep . Proper resilience can be created within a remarkably thin profile assuming that layer is truly resilient.

design practice and since test results for a given wall or Floor will vary by a few points a 3-5 dB margin of safety is recom-mended. It is also prudent to examine the range of test results for a given configuration and to expect the lowest val-ues in the test range rather than the highest. The medium-quality level is appropriate for use in high-
|How Loud Is Too Loud: Decibel levels of common sounds|
Sound Advice Decibels are in essence a measure of volume. The volume or intensity of sound is measured in units called decibels dB generally on a scale from zero to 140 any higher than 140 and you are in trouble immediately . The higher the number in decibels the louder the noise. The louder the noise the greater the risk of hearing loss.

Examples. If the numerical value of the reference is undefined then the decibel may be used as a simple measure of relative amplitudes. As an example assume there are two loudspeakers one emitting a sound with a power P 1 and a second one emitting the same sound at a higher power P 2.Assuming all other conditions are the same then the difference in decibels between the two sounds is given by:
