Building Acoustics

Building acoustics measurements depend on several pieces of equipment working accurately as a system. Campbell Associates can support the instruments used for airborne sound insulation, impact sound insulation, façade testing, room acoustics and reverberation-time measurements.

What we calibrate

We calibrate a wide range of professional sound and acoustic measurement equipment, from complete sound level meters and noise dosemeters to individual microphones, preamplifiers and environmental monitoring systems. We support most leading manufacturers, including both current and legacy instruments.

Building Acoustics Sound Level Meters

Class 1 instruments and acoustic analysers configured for sound-insulation and reverberation measurements.

Complete Building Acoustics Kits

Meter, microphone, calibrator, tapping machine and source equipment assessed as a coordinated test kit.

Measurement Microphones / Mic Sets

Microphone capsules, preamplifiers and complete Mic Sets used with building-acoustics analysers.

Acoustic Calibrators

Class 1 and compatible Class 2 reference calibrators used before and after building-acoustics measurements.

Tapping Machines

Standardised five-hammer impact sources used for floor impact sound-insulation testing.

Dodecahedron / Omnidirectional Loudspeakers

Directivity verification for measurement sound sources used in airborne sound-insulation tests.

Power Amplifiers

Amplifier and source combinations used with omnidirectional loudspeakers; publish only if the lab confirms a defined verification method.

Reference Sound Sources

Calibrated/qualified acoustic sources used for comparative measurements; competitor benchmark suggests demand.

Signal Generators / Noise Sources

Integrated or standalone source generators used to excite rooms for sound-insulation and reverberation tests; verify Campbell method.

Impulse Sources / Clappers / Impact Balls

Building-acoustics accessories such as clappers and impact balls; candidate service depending on lab fixtures and method.

SITMA Calibration Package

One-stop package for SITMA members: Campbell publicly describes UKAS calibration plus tapping-machine precision measurement and loudspeaker directivity/stability evaluation.
