A sound level meter is the instrument used to calculate the sound pressure level. It is extensively used in the research work relevant to sound pollution for different sound qualifications specifically for industrial, environmental and aircraft noise.
This post will explain to you what a SPL meter is and how to use it? It measures various types of unpleasant noises.
Usage of SPL Meter
The SPL meter comprises of a mini microphone for accepting the sounds and transferring an electric signal. It also has an electronic circuitry for the operation of various signals to measure desired features. This indicating device is the digital SPL meter to read the sound level in DB. Hearing threshold is almost Zero dB for pain threshold and young listeners is almost 120 dB.
Calibrating home theatre system in our home is important for home entertainment. But it takes just a few seconds to achieve. The usage of dB SPL meter works marvels in this respect. It measure decibels coming from speakers and assists you to fine tune the system for best ...
... outcomes. Initially, you should turn the receiver on and have the remote of that receiver. Next, grab the SPL meter and sit on the chair. Well, it is the time to calibrate.
Caveats while using SPL meter
You should place SPL meter straight up and also close to your ear. It will be best to put on a tripod so that you can conveniently stand before a meter to get precise reading. It is better to set the meter to slow response or weighting.
At the beginning, the sound level for every channel should be zero. Lest having negative fonts, offset every channel accordingly. You can also set the control of engine dyno according to the receiver. If volume scale goes from negative to positive, then you should use 0. Comparatively, if volume scale shows 0 values, then you should pick the scale showing at 80 percent range. It is the time to commence the test tone and modify the noise level near to 75 dB on the SPL meter. It provides you the preference level where you can use any number for the calibration and volume setting. It will move the sound tone to the next channel within a few minutes. However, there is no requirement to be concerned. As you can change the channel once you want to move to another channel, it needs various cycles so you can get inexpensive SPL meter conveniently from online or offline shops. These meters are ideal for audio and general implementations in warehouses, pubs, clubs, schools, warehouses, manufacturing units so that you might provide an environment-friendly setting to your staffs.
