|B&K 2260E : Sound Intensity Analyser||£ 42 a day *|
Hand-held 2260 meter with the BZ 7205 intensity software.
The combination of 2260E and the 3595 Sound Intensity Probe Kit enables :-
Flanking and Leak Detection investigations as well as
Sound Intensity measurements of Sound Reduction Index to BS EN ISO 717-1.
|B&K 2250 RT : Reverberation Time Meter - with BZ 7227 software||£ 36 a day *|
The Reverberation Time Software BZ-7227 enables the B&K 2250 to make Reverberation Time (RT) measurements.
Press the Start button, clap your hands and that's all it takes to do a basic measurement in small rooms. The traffic lights shows measurement status at a glance, and the resulting RT spectrum is shown as well as the average RT, reverberation time for the room. Alternatively for large spaces use the built-in noise generator plus an amplifier speaker system.
Keep track of measurement positions in the colour map display, check the indicators for measurement quality, and add spoken or text comments to positions or projects.
Measurements comply with the relevant parts of BS EN ISO 3382 and other Standards.
|B&K 3207 : Noise Impact Tapping Machine||£ 15 a day *|
A 'foot steps' impact noise generator, for Impact Insulation Measurements to national and international standards
BS EN ISO 140 and BS EN ISO 717
For hire as stand alone instrument or part of a Building Acoustics Kit
|B&K 3361 : RASTI - Speech Transmission Meter||£ 24 a day *|
The Bruel & Kjaer 3361 measures RASTI and related parameters directly.
RASTI - Rapid Speech Transmission Index is a method for measuring speech intelligibility - for example in a lecture hall or over any public address system. The 3361 has two components:-
4225 - RASTI Transmitter - sends out a special test signal, either directly or over the PA system
4419 - RASTI Receiver - analyses the signal and calculate the RASTI and other values.
|Nor 118+ : Building Acoustics Analyser - single channel||£ 32 a day *|
Norsonic single channel acoustic testing and room acoustics analyser with internal noise generator and RT calculator - ideal for survey work. ***
Acoustic Insulation Ratings are made using the results and the tables in the relevant Standard(s). ***
We supply complete kits, or just order a noise output cable so you can use your own amplifiers, speakers etc., and add a tapping machine, sound impact if required.
*** For fully automated systems see the B&K 2250 or 2260D systems above.
