Sound Sources And Amplifiers
A sound source that fulfills the standards for building acoustic measurements is required for professional use. Brüel & Kjær offers a complete range of sound sources for room and building acoustics, including our Tapping Machine, and 12-speaker omnidirectional OmniPower™ Sound Source. The sound sources are ideal with our range of Power Amplifiers and provide a flexible setup for any acoustic task with features such as wireless signal transmission for unhindered measurement range and flexibility.
OmniPower Sound Source Type 4292-L is a a dodecahedral, high-power, omnidirectional loudspeaker designed to measure sound insulation and perform room acoustics measurements.
Wideband Volume Velocity Sources
Ready to use Volume Velocity Sources incorporating special <br>two-microphone design for precise, in situ measurement of volume velocity in real time. Suitable for a range of acoustic environments from enclosed condition close to tyres or engine components, or open conditions some distance from a reflecting surface
A powerful, compact, and lightweight power amplifier with an integrated signal generator and wireless remote-control capabilities. HBK 2755 is ideally suited for room and building acoustics measurements, as well as source path contribution (SPC) measurements driving HBK’s sound sources
A compact, highperformance, 2 × 35 W power amplifier designed for electroacoustic and general-purpose applications.
Tapping Machine / Impact Sound Source
Tapping Machine Type 3207 is an impact sound generator for measuring impact sound levels. The generator uses five hammers each weighing 500 g and operating at 2 Hz dropping from a height of 40 mm, giving an operating frequency of 10 Hz.
Echo Speech Source quickly and easily performs speech intelligibility measurements in accordance with IEC 60268-16.
Reference Sound Source is optimized for measuring room and building acoustics. It is also useful in the field of building acoustics to determine the sound absorption and sound insulation of a room.
