The sensitivity of the microphone is determined absolutely by primary calibration technique based on the reciprocity principle. The free-field calibration has the inherent problem due to the weak signal received in the microphone. Multi-path noises s

Time-selective windowing techniques, which effectively remove multi-path noise, have been widely utilized for reciprocity calibration of microphone there are still limitations imposed by overlapping signals, particularly at low frequencies and for hi

An elastic cantilever is used for the measurement of the mass of a small quantity, by measuring the shifted resonant frequency when the unknown mass is attached to the free end of the cantilever. The measurements of resonant frequencies of the cantil

The measurements of acoustically generated temperature difference between the two ends of a TAC (thermoacoustic couple) in a resonant tube are made using the similar method suggested by Atchley et al. [J. Acoust. Soc. Am. 88, 251–263 (1990)] with a

A few-mode fiber-optic resonant ring interferometer was fabricated. Using prism output coupling, we examined the intensity variation of the radiation pattern with phase shift in the sensing arm and could easily determine the phase difference by selec
