Use Measurement Preparation For Sound Level Meter

Shenzhen Flus Technology Co.,Ltd | Updated: Nov 02, 2017

The measurement readings of the sound level meter are obviously low or the school is not $number. 0dB, microphone sensitivity is too low or damage: replace the microphone and recalibrate. preamplifier Contacts and microphone contact is not good: cleaning contacts, preamplifier Plug and host socket contact is not good: replace plug socket. The sound level meter of the low level measurement when the reading is high, the former amplifier's ground contact is not good: tighten the jacket tube. Sound Level Meter

The sound level meter displays no display: The internal battery connection is disconnected or the battery contact is not good: welds the connection, replaces the battery contact piece. Battery damage: replace battery.Sound Level Meter

The sound level meter can measure the noise to less than 20 db. Up to 100 db? and can be used to help replace the different sensitivity of the microphone to expand the scope of measurement. The sound level meter can measure the noise frequency range as low as 20 khz, up to 10000 khz. Sound level score for ordinary sound level meter and precision sound level two class? The accuracy of the former is ± 2 db? The latter is of ± 1 db. When measuring mechanical noise or vibration with a sound level meter, in addition to measuring the total noise level, the spectrum characteristics of the noise can also be measured.Sound Level Meter

The sound level meter can be divided into the precision sound level meter and the ordinary sound level meter according to the precision. The measurement error of the precision sound level meter is about 1dB, and the ordinary sound level meter is about the Earth 3dB. Sound level meter can be divided into two categories by use: One is used to measure steady noise, the other is used to measure unsteady noise and impulse noise.Sound Level Meter 

The integral sound level meter is used to measure the equivalent sound level of the unsteady noise in a period of time. The noise dosimeter is also an integral sound level meter, which is mainly used to measure the noise exposure. The Pulse sound level meter is used to measure the impulse noise, which accords with the response of the human ear to the pulse sound and the average time of the human ear to the pulse sound response.Sound Level Meter
