The Use of Miniature Electret Microphones in Small Optoacoustic Cells.
Abstract
Subminiature electret microphones were used in miniature spectrophone tests. Data has been obtained from gas mixtures with pressures as high as 660 Torr down as low as 2 Torr of CO2. Line broadening effects are very noticeable throughout the lower pressure region. Results show that subminiature electret microphones are competitive with other transducers in spectrophone work.
