Impact noise and walking noise in multifamily housing
Jerry G. Lilly · The Journal of the Acoustical Society of America · 2007
Field measurements of impact sound transmission using the ISO standard tapping machine are compared with field measurements of human walkers in both wood and concrete buildings. In wood frame construction, low-frequency noise dominates the spectrum with most floor coverings. In concrete buildings, high-frequency noise is the controlling factor in non-carpeted areas. The relative effectiveness of different noise mitigation measures will also be discussed.
