Sound Level Meter
A Sound Level Meter (SLM) is a precision instrument used to measure the intensity of sound in an environment. It quantifies sound levels in decibels (dB) and is widely used in industrial, environmental, and occupational health applications. Sound Level Meters help monitor noise pollution, ensure workplace safety, and comply with regulatory standards. Modern devices often come with digital displays, data logging, and frequency weighting options.
|
Measurement Range: |
Typically measures from 30 dB to 130 dB, covering very quiet to very loud environments. |
|
Frequency Weighting: |
Supports A, C, and Z weighting to match human ear sensitivity or specific measurement standards. |
|
Time Weighting: |
Options like Fast, Slow, and Impulse for capturing fluctuating or transient sounds. |
|
Digital Display: |
Clear LCD or LED display showing current sound level, peak levels, and often minimum/maximum readings. |
|
Data Logging: |
Some meters can store measurements for later analysis or connect to a computer for reporting. |
|
Accuracy: |
High-precision microphones for accurate sound measurement, often compliant with IEC 61672 Class 1 or 2 standards. |
|
Portable & Lightweight: |
Handheld design for easy use in the field.
|
|
Additional Functions: |
Peak hold, auto-ranging, backlight display, and sometimes frequency spectrum analysis. |
|
Power Supply: |
Usually battery-powered, with low-power consumption for extended field use.
|
|
Environmental Suitability: |
Can be used indoors or outdoors; some models are weather-resistant. |
