Why Choose NoiseDecib
High-Precision Sound Level Meter Calibrator for UK Professionals
The NoiseDecib Sound Level Meter Calibrator is engineered for acoustic technicians, environmental health officers, and occupational safety managers who demand uncompromised accuracy in the field. Essential for verifying decibel measurement instruments prior to and immediately following noise surveys, this device guarantees compliant, legally defensible data under UK Control of Noise at Work Regulations.
Dual 94 dB & 114 dB Signal Generation
Featuring an intuitive single-switch interface, the NoiseDecib calibrator generates highly stable reference sound pressure levels of 94 dB SPL and 114 dB SPL at a precise 1000 Hz frequency. The 94 dB setting provides standard background calibration, while the elevated 114 dB output enables reliable sensor verification even in high ambient background noise environments.
Universal Compatibility & Robust Field Design
Equipped with a precision-machined 1/2 inch microphone cavity and an included 1 inch adapter, the device fits seamlessly over standard electret condenser and measurement microphones. Wrapped in a durable impact-resistant casing, it thrives in field surveys across construction sites, industrial plants, and ambient outdoor surveys.

Customer Reviews
Essential tool for my industrial noise risk assessments. The dual 94dB and 114dB switch makes pre-survey calibration effortless, even on busy factory floors. Great UK customer support too.
As an environmental health officer, I need absolute confidence in sound level meter calibrator uk performance. This unit fits our 1/2 inch sound meters tightly with zero air leak. Superb value compared to Cirrus or Brüel units.
Solid build quality and holds tone stability remarkably well. Arrived next day in Scotland in a neat protective case.
Extremely accurate 1kHz tone. Fits our Class 2 acoustic calibrator requirements for workplace assessments. Only minor critique is the battery compartment latch is a bit stiff initially.
Bought to replace an old Reed unit. The 114 db 1 khz sound calibrator output is clear and stable. Highly recommend for any UK acoustic engineer.
Works perfectly with our 1 2 inch microphone acoustic calibrator setup. Reliable reference signal for outdoor acoustic mapping.
Order process was smooth and dispatch was quick. The calibration tolerance is spot on when verified against our bench meters. Unbeatable for under £130.
