| Noise and Vibration Recording and Analysis - Expertise and Practical Experience
We probably have more experience (going back over 30 years...) and expertise in the practicalities of field noise and vibration recording and analysis than any other organisation. We developed the first bespoke noise nuisance recorder and were at the forefront of the fledgling PC based analysis capabilities in the 80's. All our consultants have always had recorders for site work (recording from both sound level meters and vibration meters) so we can provide unparalleled and practical technical support for our own hardware and software and for that of other organisations. Past projects where organisations have invested in both our equipment and expertise have ranged from environmental noise monitoring to tunnel vibration analysis to product development and testing to engineering diagnosis.

Low Cost, Solid State Digital Noise Recording and Analysis - save £000's
 You can turn virtually any sound level meter into a calibrated, high quality noise recording system for around £200
- a saving of around £4000 or more over the top of the range  meters with built-in recordings. We have tested many recorders, but the two we use ourselves are the M-Audio and Marantz devices illustrated here (readily available on the web). Connect the AC output lead from your simple sound level meter, et voila - calibrated Type 1 or 2 specification recordings. Download via USB onto your PC, open in FrequencyMaster or NoiseMaster and you have a very simple to use, yet very sophisticated analysis facility (including narrow band tonal noise analysis) that is still only half the cost of an up-market meter - and can be used by everyone. This approach not only dramatically reduces costs (endowing your old meters with top-of-the-range-capabilities), but it also improves analysis quality and productivity.

echo Noise Nuisance Recorder - Two Recorders for the Price of One....
2010 Udate
The echo recorder is based on a simple premise: in most cases, you just need a low cost noise nuisance recorder that is very reliable, easy to use and produces high quality recordings. echo means that you can now afford two recorders for the price of one. Further cost savings can also be made if you need a direct replacement for old DAT based systems - contact us to see if you can re-use the microphones and other accessories.
The package can be upgraded to include the unique “unreal-time” i-Player review software, allowing you to listen to a 1 hour recording in only 6 minutes, cutting the recording processing time by 80% and providing a simple way to evaluate low frequency sounds.
"Buying several echo recorders has proved to be an ivestment that is saving us a small fortune. We have been able to improve our noise service dramatically, despite having two fewer staff than would otherwise have been necessary."

Noise Nuisance Recording Made Simple
As the developers of the first bespoke noise nuisance recorder (DAT based), we have more experience than anyone else in the design and use of complainant operated recorders. This expertise has been incorporated into the design of the latest generation of digital noise recorder to make it the simplest to use, despite the extensive range of unique features. Arrive, plug-in microphone, auto-calibrate, auto-voice log, close and lock case, leave. Single button complainant operation, a discrete carry-case and the ability to reduce the (boring) time spent processing recordings by a factor of x10 makes this the noise nuisance recorder of choice for EHOs who would like to spend their time more productively.
NOTE: DAT Noise Nuisance Recorders
These are no longer available as Sony has discontinued the DATs. We have replaced them with a new generation of solid state recorder. However, we still support our DAT noise nuisance recorders - maintenance, calibration etc..

Noise and Vibration Analysers
FrequencyMaster - low cost narrow band frequency analysis made simple
".. a terrific piece of kit.." Terry Croker, Compair (industrial engineering testing)
".. excellent piece of software; easy to use. can't really think of any improvements." Keiran Smith, S Shrops Council
Typical Current Applications for FrequencyMaster include:-
- environmental noise analysis - BS4142, diagnosis, prediction
- environmental and occupational noise control - diagnosis
- fault diagnosis - noise and vibration frequency analysis for engineers
- product testing - noise and vibration frequency analysis
- training - noise and vibration analysis and visualisation
New version 3 of the best selling frequency analyser - now with unique i-Player facilities for high speed subjective sound processing.
Narrow band frequency analysis is a very powerful and useful tool for environmental assessment, source identification, noise and vibration control, machine fault diagnosis and many other applications. The main barriers to widespread use have been a combination of cost and the shear "user hostility" of most FFT analysers. We have removed these barriers. New technology has allowed us to change the rules of  the game as far as frequency analysis is concerned.
FrequencyMaster makes sophisticated analysis and display techniques accessible to everyone at little more than the cost of a replacement microphone. Real time FFT, 1/1, 1/3 octaves; 3D waterfall plots; digital recording to disk; plot overlays; time trace; data export ...
FrequencyMaster can also be used to upgrade to provide tonal analysis for existing systems as it can process sound files from virtually any source, individually or in batches. Alternatively, you can take FrequencyMaster into the field for live frequency analysis by installing it on a low cost netbook or tablet PC when you can take full advantage of the user interface and recording facilities.

iPlayer: Unique Accelerated Listening - reduce subjective sound recording analysis time by 90%...
iPlayer facilities are built-in to the latest versions of both FrequencyMaster and NoiseMaster. Based on our own experience of the time consuming hassles involved in listening to interminable complainant recordings, the iPlayer is an invaluable tool that decimates the time taken to process the files (avoiding incipient "athletes ear"...). The key features are:-
- intuitive in use - very graphical with no learning curve and nothing to remember
- reduces the subjective processing time for recordings by c 90%
- low frequency identification facilities - helps resolve those difficult and time consuming low frequency noise complaints
NoiseMaster - sound file analyser and logging noise monitor and recorder
Some of the key NoiseMaster applications and features include:-
- high speed automated analysis of sound files from any system - speeds up analysis
- direct export into iPlayer (subjective analysis) or FrequencyMaster (frequency analysis)
- long-term environmental noise monitoring with sophisticated triggering of sound file recording
- SMS text message alerts when consent conditions are exceeded - real-time feedback
- automated engineering product noise and vibration testing
 Noise Master combines the facilities of virtually every sound level meter and logging noise analyser you can imagine with those of an automated digital recorder. It breaks yet further with tradition by making these facilities simple to use - and by providing them at a low cost. Whether being used for post-processing batches of sound files from virtually any recording system or for real-time noise analysis on a construction site, NoiseMaster makes sophisticated noise analysis simple.
It not only allows you to make digital recordings of types of event for identification and frequency analysis (and exporting directly into FrequencyMaster), but also allows you to look at noise variations in detail and try instant "what if" re-analyses using different measurement parameters. Parallel Lns; Leq; Lmax/min; digital recording to disk; 3D plots; re-analysis of logged data; remote communications ...
