H-AR-D Recorder - Low Cost Solid State Noise Nuisance Recorder

NEW V4: The next generation low cost, solid state, touch-screen Noise Annoyance Recorder. This is the simplest noise nuisance recorder to use and is the most efficient system available, reducing the time required to to process recording by an order of magnitude compared with any other system.

Unique “unreal-time” i-Player
... increasing the speed of sound ...

Use the integrated i-Player software to listen to a 2 hour recording in only 12 minutes! Process recordings in <10% of the time. Simplify low frequency and tonal sound identification via frequency analysis.

• Solid state recording medium - robust USB key
• Auto-calibration and Auto-record quality (Type 1 specification)
• Auto-time and date and Auto-archive
• Auto-analysis (frequency and statistical)
• Listen to recordings on site; control maximum recording time...

Unique end-to-end Type 1 specification covering measurement and recording and re-analysis, not just initial SLM measurement parameters

Time Travel!   -  Event Recording  -  Timer Recording

Pre-trigger allows you to start recording events before they have happened ... Record events automatically using unique triggering that can be tuned to particular types of event... VCR mode for unattending timed recording.

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 - frequency analysis made simple

New version 3 of the best selling frequency analyser - now with unique i-Player facilities for high speed 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 ...

NoiseMaster - logging noise recorder and analyser

Noise Master combines the facilities of virtually every sound levelmeter 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. NoiseMaster makes sophisticated noise analysis simple. It not only allows you to make digital recordings of types of event for identification and frequency analysis (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 ...

Training, Recording Analysis

We have trained 100s of people in recording and analysis techniques. We also provide recording analysis for diagnosis and court cases.
