[Acoustic transmission characteristics of the human thorax at various frequencies (author's transl)]. 1977

A Aigner, and M Wieser, and G Müller, and E Raas

The acoustic transmission characteristics of the human thorax in the frequency range of 100 to 2000 c.p.s. were studied in nine corpses. Using a logarithmic scale for frequency, the sound pressure level measured on the chest wall showed a linear attenuation between 100 and 1000 c.p.s. with a mean reduction in sound pressure level of 77 dB.
