What does sound calibration mean?

What does sound calibration mean?

The most basic part of theater audio calibration is making sure that all of the speakers’ levels are balanced. It is critical for accurate sound that none of the speakers is too loud or soft with respect to the others.

How is a sound meter calibrated?

It involves using an acoustic calibrator that is usually supplied as part of your measurement kit. The acoustic calibrator fits over the microphone and outputs a consistent sound level for the microphone to detect. The software in the sound level meter knows what the output from the calibrator should be.

What do you mean by sound level meter?

sound-level meter, device for measuring the intensity of noise, music, and other sounds. A typical meter consists of a microphone for picking up the sound and converting it into an electrical signal, followed by electronic circuitry for operating on this signal so that the desired characteristics can be measured.

What is auto sound calibration?

Auto Sound Calibration automatically optimizes the 5.1 channel sound. It is necessary to adjust each channel for the sound quality on various functions in a Samsung Home-Theatre system according to the characteristics and location of the speakers and the environment.

What is sound calibration microphone?

Laboratory standard microphones calibrated using this method are used in-turn to calibrate other microphones using comparison calibration techniques (‘secondary calibration’), referencing the output of the ‘test’ microphone against that of the reference laboratory standard microphone.

How do you use a sound calibrator?

Using a Sound Calibrator All sound level meters have either an adjustment screw or some form of automatic calibration feature. Carefully place the calibrator over the microphone, ensuring it is a snug fit, and switch it on. Check that the display reads the level that will be specified in the manual.

How do you use a noise level meter?

How to Use a Sound Level Meter

1. place the sound level meter at a sufficient distance from any obstacles or reflectors.
2. place the microphone of the sound level meter about 1,3 – 1,5 m above the ground.
3. place the microphone of the sound level meter in the direction of the sound source.

What is a sound level?

Sound level refers to various logarithmic measurements of audible vibrations and may refer to: Sound exposure level, measure of the sound exposure of a sound relative to a reference value. Sound power level, measure of the rate at which sound energy is emitted, reflected, transmitted or received, per unit time.

What is channel level adjust?

Adjusting the volume of each channel to match the input source (Channel Level Adjust) The volume of each channel can be changed while listening to music. You can set this for each input source.
