Royston, Herts, United Kingdom, 2013/12/12 - To help environmental officers and consultants reduce time spent conducting multi-point acoustic measurements, Brüel & Kjær has launched a 2 Channel Option for its Type 2270 sound level meter - BKsv.com.
The new 2 channel option on the 2270 allows both channels to receive simultaneous input, from two microphones or accelerometers. It can also receive feedback from one microphone and one accelerometer. This allows the user to carry out synchronised acoustic or vibration signal measurements, making it ideal for interior/exterior noise measurements or assessing how vibration from machinery relates to its noise output.
The 2 channel option is also compatible with Signal Recording Option BZ-7226. This is a signal recorder application which enables the other optional modules to record the input signal, as an attachment to a measurement project, allowing the user to identify and document sound and vibration sources, such as HVAC units, transport noise or wind turbines.
The user can play back their recordings and export the data for further analysis via Measurement Partner Suite, which is a post-processing software for the company’s 2250 and 2270 sound level meters. Measurement Partner Suite automates the most common post-processing tasks, removing the need to export data to spreadsheets for analysis and saving hours of a consultant’s time. In addition, the risk of errors when using and sharing spreadsheets is reduced.
Measurement data can be quickly emailed to other users with a ‘pack-and-go’ feature that zips and sends entire measurement archives with one click. The archive then reappears in the recipient’s display automatically.
The updated software also offers a Low frequency option for the 2270 and 2250 meters. With the low frequency option enabled - and the appropriate transducer selection - infrasound and building vibration measurements can be performed according to the most important international standards, such as ISO 7196:1995 and ANSI S1.42 2001(R2011).
