Noise Monitoring Terminal Type 3639

Noise Monitoring Terminals Type 3639 are a range of powerful, modular, noise monitoring terminals, optimised for outdoor use.

With a custom-designed enclosure, the Noise Monitoring Terminal (NMT) is designed for use in all climatic environments, as well as industrial, urban and rural conditions.

It is an intelligent unit that can be left unattended as part of an environmental noise monitoring system for permanent, mobile or semi-permanent monitoring. With selectable communication and central control software, the Noise Monitoring Terminal can be controlled by a remote PC.

Uses

• Permanent and semi-permanent monitoring for:
  • Aircraft and Airport noise
  • Road noise
  • City noise
  • Train noise
  • Industrial noise
  • Noise surveys

Features

• Designed for stable, long-term, continuous outdoor monitoring
• Logging of broadband and 1/3-octave (optional) parameters every second or 1/2-second
• Streaming of data over LAN to Environmental Noise Management Software Type 7843
• 40GB industrial hard disk for safe, long-term back-up
• Post-processing that can create periodic statistical reports down to 1 minute, including LN data
• Dynamic range of 110 dB
• Remote verification of the entire measurement chain using the patented Charge Injection Calibration (CIC)
• GPS support
• Sound recording (optional)
• Weather-data monitoring (optional)
• Camera support (optional)
• Remote operation via LAN, public telephone lines, mobile phone or GPRS
• Modular hardware/software for easy on-site servicing
• Noise event triggers can be defined on an hourly basis for more effficient noise detection

Additional Features in Latest Version:

• Time-based sound recordings: Record sound at user-defined time intervals and durations for, for example, 1-minute sound recordings to be made at the start of every one hour in order to identify typical sound environments
• Wav file recording for analysis: Record events as high-quality WAV files for post-processing, such as tone analysis using FFT in e.g. Brüel & Kjær’s PULSE
