Metrology Glossary: Sound Meter

What Is A Sound Meter?

A sound meter, also known as a sound level meter or decibel meter, serves as a tool for quantifying the magnitude of sound. This handheld instrument is designed with a built-in microphone, responsible for the conversion of sound waves into electrical signals. The meter processes these electrical signals to determine the sound intensity in decibels (dB). Sound meters are generally categorized into two classes, with their precision and capabilities determining their classification. Class 1 sound meters stand out as the most precise instruments. Class 2 sound meters, while somewhat less accurate, offer a more cost-effective option.

What Are Sound Meters Used For?

Sound meters are essential for many applications. They can be used for occupational noise monitoring, ensuring workplace safety and preventing hearing loss. They contribute significantly to environmental noise assessment, evaluating and controlling noise levels in various settings. In building acoustics, these meters provide vital data for architects, ensuring optimal acoustic comfort. Audiometry tests benefit from their use in assessing hearing sensitivity and diagnosing hearing loss. Additionally, sound meters play a key role in product noise testing, aiding manufacturers in designing quieter products that meet noise emission standards. Their versatility spans occupational safety, environmental control, architectural design, healthcare, and product development, making them indispensable tools across diverse domains.
