Finding the Perfect Sound Level Meter for Your Applications

The sound level meter is among the most important instruments for many companies and industries. Many industries use this to maintain sound, and many use it to check whether the machines are working perfectly or not. It totally depends on your application and which sound level meter you require. You need to read this blog to understand the best sound level meter for your application.

What is Sound Level Meter?

A sound level meter is a measuring device used to quantify a sound’s sound pressure level (SPL) in decibels (dB). It is used to assess a sound’s loudness in various environments, including industrial, occupational, and environmental settings. Sound level meters typically consist of a microphone, amplifier, and display that provide real-time readings of sound levels. They are often used to measure noise pollution, evaluate safety and health, do acoustic research, and set up and improve sound systems.

How Does It Work?

The measurement range of a sound level meter is determined by its sensitivity, which is the minimum sound pressure level that can be accurately measured, and its maximum level, which is the highest sound pressure level that can be measured without damage to the meter or the microphone. Sound level metres can be set up to use international standards, such as the A-weighted or C-weighted decibel scale, to measure sound pressure levels.

1. The amplifier amplifies the electrical signal.
2. The amplified signal is converted from analogue to digital form by the ADC.
3. The digital signal is displayed on the meter’s display or logged for further analysis.
4. The measurement range is determined by the meter’s sensitivity and maximum level.
5. Sound level meters can be calibrated according to different international standards.
6. Different sound level meters are available, including those that integrate, average, and peak.
7. The choice of sound level metre depends on how it will be used, where it will be measured, and how accurate it needs to be.

Types of Sound Level Meter

Different types of sound level meters are available, including integrating, averaging, and peak level meters. The choice of sound level meter depends on the intended use, measurement environment, and desired accuracy. Following are the four types of sound level meters that vary in quality.

1. Class 1 Sound Level Meter: This meter is the most accurate and precise, with a wide measurement range. It is commonly used for laboratory testing, calibrations, and critical noise assessments.
2. Class 2 Sound Level Meter: This metre isn’t as accurate as Class 1, but it’s still good enough for most noise assessments in industries and the environment.
3. Class 3 Sound Level Meter: This meter is less accurate and precise than Class 1 and 2, but is still suitable for general noise assessments and environmental monitoring.
4. Class 4 Sound Level Meter: This meter is the least accurate and precise but is still suitable for basic noise assessments and general environmental monitoring.

It’s important to choose a sound level metre that has the accuracy and precision needed for the application and the measurement range needed to get the level of detail you want in the data.

Sound Level Meter Applications
