NoiseLog_mobil

PTB approved, long-term noise and vibration monitoring system

Overview

Traffic forecasts by the German Federal Ministry of Transport and projections on the industrial development show that the noise pollution emitted by road and rail transport, airports and industrial plants will increase significantly. Usually hand-held sound level meters are used to determine the sources of noise pollution . Depending on the type of the sound source, however, PC-based measurement systems may offer better analysis capabilities.

Commercially operated facilities and industrial plants which require a permit and must adhere to the regulations of the Federal Immission Protection Act (Bundes-Immissionsschutzgesetzes - BImSchG) are covered by the technical instructions on protection against noise (Technische Anleitung zum Schutz gegen Lärm - TA Lärm) with respect to the evaluation of the caused noise emissions. According to Art. 26 BImSchG, authorities and metering points for the determination of noise emissions and immissions shall use officially calibrated sound level meters for the noise pollution evaluation. With Soundbook and NoiseLOG_mobil we offer calibratable, PC-based measurement systems with up to eight measuring channels for capturing environmental noise data using the latest technology. The post-processing of measured values with Auditor, MS Excel or other applications can be performed directly on the Soundbook.

The Soundbook-based NoiseLOG_mobil is designed for rough field operation as for example at construction sites. The measuring station continuously monitors noise and vibration at one or more measurement points. To match the specific requirements of an application up to eight different microphone types, geophones and accelerometers in our product range may be directly connected to the NoiseLOG_mobil. All relevant data as sound level curves, 1/3 octave spectra and audio signals are locally stored for long time periods. Access for the evaluation of the stored data is already possible during measurement. NoiseLOG_mobil allows integration into various networks via LAN, ISDN, modem and GPRS. Several microphone types also offer automatic periodic sensitivity monitoring using electrostatic actuator calibration.

The measurement system may be complemented with different meteorological sensors. For the connection of external alarm channels floating contacts are available. Various interfaces allow acquisition of additional information as vehicle speed, transponder characteristics or other data. As a separate option we offer a camera for video recordings that are synchronized with the measured data. NoiseLOG_mobil is suited for the continuous monitoring of aircraft noise, industrial noise, road and rail transport noise and well as noise caused by sports or other major events. The fully automatically working station is controlled locally (service case) via a bright 10.4“ TFT touchscreen and via network for remote control. All measured data can be directly stored on a hard drive or an exchangeable SD card.
Our NoiseLOG_mobil measuring stations may be equipped with various software products to meet the specific application demands. Integrated flexible system trigger mechanisms ensure that all relevant data are captured and stored. High-performance signal processors allow real-time processing of the measured data. Data storage on a hard drive, network communication and statistical evaluation are safeguarded by a powerful, highly reliable Panasonic Toughbook PC. NoiseLOG_mobil works with a Windows 7 operating system and allows full control via a remote computer.

The portable NoiseLOG_mobil comes in a sturdy IP65-protected ABS carrying case. The internal battery of NoiseLOG_mobil offers an operating time of up to 15 hours. For installation of the measuring microphones in the field we offer various MIL-compliant telescoping masts which allow easy transport and installation in just a few steps. We also supply the ready-to-use NoiseLOG_mobil station in various passenger car trailers. We will mount optional hardware accessories as a pneumatic telescoping microphone mast, weather station or WiFi antennas before delivery. The trailers offer a 25V on-board mains, DC/AC converters and batteries including charger for 1 week of autonomous operation.
