virtually every instrument in the acoustic field can digitally check. It also offers a multitude of outputs in various frequency and different levels.
Apart from that the device is powered by batteries and mobile, making it easy to take with you. The 1986 will test the majority of characteristics of a sound-level metre according to IEC and ANSI standards. It can be utilized for all sizes and types of commonly used measurement microphones thanks to the provided and microphone cavity adapters that are oplional.
The calibrator features lones with the six different frequencies from 125 Hz to 4000 Hz in octave stages along with five distinct levels of sound pressure ranging from 74 to 114 decibels in five l (‘dB increments. The calibration also includes the sensitivity test of an audio instrument with respect to frequency and measure levels.
The Omnical Sound-Level Calibrator , which was released in 1986 is able to measure virtually any acoustic instrument system’s fundamental properties. The tone can also be calibrated with a battery-powered handheld instrument.
There are six frequencies the calibrator measures including 125 Hz and 4000 Hz, in various octave levels. It also has five different levels of sound pressure that range from 74 to 112 dB per l (in “dB steps). This calibration is also accompanied by an audio instrument sensitivity test in the frequency range and at the measurements level.
You can also test the frequency response of audio-measurement devices, weighting networks, and filters. u4mlshph38.
