Masking and Filtering Sound
NASA's Glenn Research Center has produced an educational CD,
"Auditory demonstrations in acoustics and hearing conservation".
This excellent arrangement of demonstration tracks, provides recordings
of common noises, their "usual" levels, escalated levels, and the same
noises with masking and filtering applied. This CD clearly demonstrates
the effects of these agents on both tonal and broadband sounds. In fact,
masking and filtering and the use of "white noise" have become useful
weapons in the war against unwanted sound and noise. To download the
intriguing CD produced by NASA, Auditory Demonstrations in Acoustics
and Hearing Conservation Featuring the sounds of NASA Glenn Research Center
