WebWhen the pistonphone is operating properly, the LED is green, indicating that the speed of the cam is correctly locked to give 250 Hz. If it is red, while the pistonphone is switched on, the speed is incorrect and most likely because of low batteries. The operating procedure is straight forward: simply fit the microphone into the coupler of the WebCoupling adaptor (for Model 106B & Series 116B on Pistonphone) Model: 061A14.

A pistonphone is an acoustical calibrator (sound source) that uses a closed coupling volume to generate a precise sound pressure for the calibration of measurement microphones. The principle relies on a piston mechanically driven to move at a specified cyclic rate, pushing on a fixed volume of air to which the microphone under test is coupled. The air is assumed to be compressed adiabatically and the sound pressure level in the chamber can, potentially, be calculated from inte… how to feather an edge in photoshopWebThe driving mechanism of the Glover-Bauer pistonphone was a moving coil.
