What are Sound Level Meters?
Sound level meters are manual or handheld electronic equipment which can be used for accurate measurements. They offer readings primarily based on the noise level in every place and commonly turn out measurements in decibels form. They are also referred to as decibel meters or noise meters.
The majority of meters include a built-in digital display, and some also have a data logging memory to save readings. Numerous versions can be connected to a smartphone or tablet, and data sharing is simple. To export data from some models, a computer connection is required.
What is the difference between Class 1 and Class 2?
The sound meter consists of two classes, such as Class 1 and Class 2, also referred to as Type 1 or Type2. Sound meters have entitled to a classification of I or II based on the international standard they are compatible with. Because they can measure the quietest sound levels, Type 1 or Class 1 sound meters are used for extremely accurate noise measurements (such as in laboratories). In order to evaluate and measure noise in workplaces, class 2 sound meters are typically utilized.
What is the Purpose of Weighting?
Weighting means the frequency occurring that is measured. Whereas most sound meters can only measure one frequency range, other techniques are capable of measuring the rest, such as:
A frequency covers up to 20 Hz to 20 kHz range. To approximate the frequency that is perceptible to the human ear, the sound is, however, chopped from the lower and upper ends of the spectrum.
C frequency can provide a measure that consists of higher noise levels but is still capable. The frequency of sound can be felt by the human ear.
Z frequency covers the oven all frequency range between 10Hz to 20 kHz, ±1.5dB.
A technique that is used to Calibrate a Sound Level Meter
A service that is being used for calibration lets your sound meters make sure that they are responding with accurate measurements all the time. It provides you an absolute strong belief that the instruments you are installing would be the work same as you expected, even with the high accuracy.
What is a Dosimeter?
Dosimeters assess an individual's exposure to noise, whereas sound meters measure the noise in the entire area. To measure noise levels, dosimeters (also known as dosemeters) are frequently worn by employees.
What is a Sound Level Meter used for?
Sound meters will provide you with measurements of the level of noise within an environment. High noise levels can damage hearing, cause hearing loss, and can have a harmful influence on health. A sound meter's reading can help you determine whether you're taking the proper precautions (such as slowing down machinery to reduce unnecessary noise) and wearing the proper PPE (Personal Protective Equipment) to reduce risk.
