Sound-level meter from B&K measures acoustics in real-world building sites

The Brüel & Kjær HBK 2255 sound-level meter

Brüel & Kjær test and measurement solutions are available in Canada from Durham Instruments – like the HBK 2255 sound-level meter, for example. Developed specifically for measuring building acoustics, this device is all a worker needs for applications like airborne, impact, and façade sound-insulation testing when used with HBK architectural sound sources. From measurement to final report, this meter is a lightweight, robust unit that is perfect for real-world building sites with more dust and debris than in functional elevators.

High efficiency, control levels

The HBK 2255 can measure everything required for sound insulation, from 1/1- or 1/3-octave band-level measurements to reverberation time measurements with interrupted or impulsive noise signals. Among the other relevant applications: calculation of sound-insulation results according to national and international standards; detailed analysis of sound-insulation measurement, including manual adjustment of measurement data for theoretical analysis; and preparation of sound-insulation test reports as per standards. Durham Instruments deems the device suitable for general manufacturing, education, and research and development.

Connecting the instrument to the Building Acoustics Partner app enables wireless remote control and complete workflow support. This app also offers total freedom to adapt the HBK 2255 to onsite conditions, while simplifying both reporting and analysis.

The PC version of Building Acoustics Partner is designed for analyzing measurement data and creating reports in the office, all with high efficiency, with optimum insight and confidence in the information. Measurement data can be viewed in graphic or tabular form, with level-measurement info that allows quick, easy comparison of source room, receiving room, and background noise levels, plus the variability between positions of the same measurement type.

The Building Acoustics Partner mobile app adds high levels of efficiency and control to sound-insulation measurement. Measurement planning and workflow automation helps to make sure that no measurement position is ignored, while simple measurement reuse between partitions helps to minimize the total amount of measurements. Integrated wirelessness in the meter and power amplifier allows full remote control, with no need to run cables under doors. The device calculates results automatically, which enables confirmation of compliance with project targets.
