1965 New Scientist 21 Oct. 199/3 The collisional phenomenon has recently been investigated..using a device named the ‘spectrophone’, in which a sample of gas is subjected to a sequence of pulses of infrared (140 a second) during which the molecules acquire vibrational energy. If they lose that energy by collision, the increase in molecular velocities, and therefore in pressure, is detected by a microphone in the gas, which accordingly registers a 140 c/s note.
