Mobility Testing

In mobility testing, accelerance, mobility and compliance functions are calculated. For structures with well-separated modes, estimation of natural frequencies and damping ratios is possible. Often done during troubleshooting using hammer testing.

Acoustical Measurement System

When shaping a conference room for speech or a concert hall, or when dampening the sound of a gym hall, accurate acoustic measurement and reporting is absolutely crucial. To help you achieve your desired acoustic profile, Brüel & Kjær Acoustic Measurement Equipment provides a complete system for your room and building acoustics measurement projects.

ARCHITECTURAL ACOUSTICS

Architectural acoustics encompasses the fields of building acoustics and room acoustics. Building acoustics focuses on sound transmission through walls, doors and floors. Room acoustics focuses on the behavior of sound inside a room.

Please review our Glossary of Acoustic Terms

ROOM ACOUSTICS

In a room, good acoustics require a design that is fit for purpose, such as easy communication and a high degree of intelligibility in office spaces or long reverberation times in concert halls. Issues with acoustics are normally caused by sound being reflected too much, too little or in the wrong direction.

BUILDING ACOUSTICS

To limit noise from entering a room, or to understand the degree to which it penetrates, building acoustics come into play. Here we focuses on sound transmission through walls and entrances, such as noise from people or outside vehicles.
