声源

为了实现建筑声学的正确测量，声源的范围要求符合相关的标准，比如ISO140。
Brüel & Kjær的声源优化范围包括建筑声学声源，房间和部件激励的全方位声源和地板激励的打击器。

		型号

		Light - OmniPower Sound Source - 型号 4292 Types 4292-L and 4295 are designed for airborne noise transmission measurements.


		4295 OmniSource扬声器 Type 4295 OmniSource Sound Source Type 4295 presents a new solution to omnidirectional sound source design. OmniSource is optimised for the measurement of room acoustic quantities, such as reverberation time, sound distribution and spatial decay.


		带4299 型体积速度适配器的OmniSource4295型 OmniSource covers the most important frequency range for the automotive industry, that is, from 50 Hz to around 6 kHz. Volume Velocity Sources are used as "acoustical shakers" to measure acoustic transfer functions, typically in connection...


		3207型打击器 Tapping Machine Type 3207 is an impact sound generator. It can be used for impact sound measurements to national and international standards. The unit is available with an optional battery kit and a remote control.


		4204型参考声源 Reference Sound Source Type 4204 is a calibrated source of sound power with well defined operating characteristics and a predictable performance. It is rugged, compact and stable, and is therefore suitable for both field and laboratory use.


		2716型功率放大器 Audio Power Amplifier Type 2716-C is a high-performance power amplifier optimised for sound and vibration applications. It can be used as a general-purpose power amplifier for electroacoustic applications.


		2734功率放大器 Type 2734 Power Amplifier is designed to power sound sources in building and room acoustic field measurements.


		Power amplifier - 型号 2713 Designed to drive highly capacitive transducers to high voltage levels, such as when hydrophones Types 8103, 8104 or 8105 are employed as projectors in underwater calibration arrangements.
