Abstract
The speed of sound as a function of temperature (0°–3°C) and the transmission loss in 2.5-cm-thick samples of 13 different RTV silicone rubbers have been measured in the frequency range 500 kHz–1 MHz. The range of measured sound speeds for the various materials was between 960 and 1110 m/sec at 0°C. The thermal coefficients of sound speed were approximately −3 m/sec °C for all samples. The transmission losses ranged from near 0 dB for RTV-602 to 14 dB for RTV-90 at 1 MHz.This publication has 0 references indexed in Scilit:
