Sound Level Meter – Accurate Measurement of Noise and Sound Intensity

A Sound Level Meter (SLM) is a precision instrument used to measure the intensity of sound in decibels (dB). It plays an essential role in monitoring noise levels across industries, laboratories, classrooms, and public environments. Whether you are performing an acoustic study, maintaining occupational health and safety, or conducting environmental noise assessments, a sound level meter ensures accurate, consistent, and professional measurement results.

At Labtex Bangladesh (Labtexbd.com), we supply high-quality digital sound level meters suitable for educational, industrial, and environmental applications. Our meters are known for their accuracy, durability, and ease of use — helping users meet local and international standards for sound measurement.

What Is a Sound Level Meter?

A sound level meter is an electronic measuring device that detects and quantifies sound pressure levels in the environment. It typically consists of:

• A microphone to detect sound waves.
• An amplifier and frequency weighting network to filter the sound according to human hearing sensitivity.
• A digital display that shows the sound pressure level in decibels (dB).

Sound level meters are calibrated according to international standards such as IEC 61672 and ANSI S1.4, ensuring precision for professional and educational use.

The device is often used to evaluate noise in factories, schools, offices, homes, and outdoor environments, helping users maintain acceptable sound limits and comply with noise regulations.

How to Use a Sound Level Meter

1. Turn on the device and select the desired weighting (A or C).
2. Choose fast or slow response depending on the noise type.
3. Hold the meter at arm’s length, pointing the microphone toward the noise source.
4. Observe and record the sound level displayed in decibels (dB).
5. For long-term analysis, use data logging features (if available).

Proper usage ensures reliable readings and helps maintain compliance with noise control standards.

Common Measurement Ranges

• Whisper: ~30 dB
• Normal conversation: ~60 dB
• Busy traffic: ~80–90 dB
• Factory machinery: 90–110 dB
• Jet engine: 120 dB or more

By comparing these values, users can understand noise pollution levels and implement appropriate sound control measures.
