Abstract:

Tables are presented for the absorption and velocity of sound in still air at 68F 20C. The absorption is presented in dB1000 ft, dBKm, and dBsec. The velocity is presented in 1000 ftsec. The tables cover the frequency range of 12 Hz - 1 MHz and for relative humidities of 0 - 100. An appendix is included which presents analytical expressions that will duplicate the tables within 3 over all frequencies and humidities.
