Digital Decibel/ Noise Meter

• Trusted 
• Reliable 
• Very effective 
• A digital sound level meter (also called a decibel meter or noise meter) is an instrument used to measure sound intensity (noise levels) in decibels (dB). It converts acoustic sound waves into electrical signals via a microphone and displays the resulting noise level digitally.
• Very strong 
• Great experience 
• Durability 

How It Works

A microphone detects sound pressure and produces an electrical signal.
That signal is processed, sometimes with frequency weighting (e.g., A-weighting to approximate human hearing) and time weighting (fast/slow).

The result is shown as a numeric decibel (dB) value on an LCD screen.
Some meters also record data, hold max/min readings, and connect to a PC.

Common Uses

Checking environmental noise (streets, factories)
Workplace noise assessments and health/safety compliance
Sound system calibration (rooms, concerts, studios)

Consumer and DIY sound checks (home, event)

Typical Specifications

These devices usually include:
Measurement range: ~30 dB to 130 dB (sound from quiet rooms to loud machinery).

Frequency weighting: A and C (sometimes Z).

Time weighting: Fast and Slow to suit different noise conditions.

Accuracy: Often ±1.5 dB (a standard for general purpose use).

Features: Max/Min, data hold, USB/PC interface on advanced models.
