Software helps detect insulation
problems
Immediate on-screen analysis of sound insulation, using Bruel and Kjaer's new BZ-7228 building acoustics software, means that problem partitions can now be quickly identified on site
Developed for use with the type 2250 analyser, the software enables fast and simple measurement of airborne and impact sound insulation, reducing time-costly off-site evaluation and hastening any necessary remedial work Matthew Hine, sales engineer for Bruel and Kjaer UK, said: "Acoustics consultants can quickly derive accurate performance values for walls and floors enabling them to delve further into possible causes of acoustic weakness and leakage and to investigate flanking paths where partitions are likely not to comply with the stringent sound insulation standards specified by the Building Regulations." The software includes settings relevant to the appropriate British and International Standards (BS EN ISO 140 and EN ISO 717), together with Part E of the Building Regulations for England and Wales, as well as a host of standards relating to different countries

Noise dose meter data collected, analysed
Noise dose meter enables statistical analysis of noise levels to establish a general 'picture' of the noise situation, showing where excessive exposures stem from.
High shock resistant accelerometers
DC response accelerometers can withstand high mechanical shocks of up to 10 000g and have been gas-damped
The 2250 has a large, colour touch-screen and user-friendly menu system.
Taking an airborne measurement as an example, the tester is guided through measurements in the source and receiving rooms, together with background noise and reverberation time measurements in an intuitive fashion, removing the need to take extensive notes as to which measurement relates to which partition.
In addition, recyclable results (e g, time-costly reverberation time measurements) may be copied between files to save time in duplicating measurements unnecessarily.
Results can be viewed immediately on site to identify potentially weak partitioning structures.
Warning and error messages (e.g background noise corrections) allow the tester to understand the cause of the problem and to take steps to ensure that accurate measurements are undertaken.
Back at the office, results may be exported to Qualifier (7830) or spreadsheet programs.
Using identical connections to the previous 2260 analyser, the built-in pink and white noise generators on the 2250 may be used with an amplifier and speaker system such as the 2716 / 4292.
A radio transmitter / receiver may also be used to enable remote control of the sound source.
