Geonoise Asia is offering a range of solutions for noise monitoring. From a single offline system to an online noise monitoring system for an entire city.
Using the latest technology we offer mems based (Class 1 complying) on and offline noise monitoring units with automated reporting, alarms etc. from Convergence Instruments.
For noise monitoring with more elevated specifications we can offer Sonitus systems, rugged noise monitoring with unlimited possibilities such as real-time data, reporting, triggered audio recording etc.
Noise monitoring is getting more and more accepted as a means to investigate noise nuisance, some examples are:
- environmental noise monitoring
- event, concert, pub, discoteque noise monitoring (indoors / outdoors)
- constructions noise monitoring (noise and vibration)
- occupational noise monitoring (i.e factories)
- road noise monitoring (noise and vibration)
- rail noise monitoring (noise and vibration)
- city noise monitoring
- shooting range noise monitoring
- race circuit noise monitoring
- harbor noise monitoring
In acoustics, noise measurements can be performed for the purpose of measuring environmental noise. Applications include monitoring of the noise coming fom construction sites, aircraft noise, road traffic noise, entertainment venues and neighborhood noise.
The word “noise” literally means any “unwanted sound”.
Environmental noise monitoring is the measurement of noise in an outdoor environment caused by transport (e.g. motor vehicles, aircraft, and trains), industry (e.g. machines) and recreational activities (e.g. music). The laws and limits governing environmental noise monitoring differ from country to country.
At the very least, noise may be annoying or displeasing or may disrupt the activity or balance of human or animal life, increasing levels of aggression, hypertension and stress.
Health and noise
In the extreme, excessive levels or periods of noise can have long-term negative health effects such as hearing loss, tinnitus, sleep disturbances, a rise in blood pressure, an increase in stress and vasoconstriction, and an increased incidence of coronary artery disease. In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfering with reproduction and navigation, and contributing to permanent hearing loss.
Various cures are available to combat Environmental Noise; Road noise can be reduced by the use of noise barriers, limitation of vehicle speeds, alteration of roadway surface texture, limitation of heavy vehicles, use of traffic controls that smooth vehicle flow to reduce braking and acceleration, tire design and not allowing vehicles (cars, motorbikes) with altered exhaust systems or without any exhaust system at all.
Aircraft noise can be reduced by using quieter jet engines, altering flight paths and considering the time of day to benefit residents near airports.
Industrial noise is addressed by redesign of industrial equipment, shock mounted assemblies and physical barriers in the workplace. Dedicated noise prediction software such as SoundPLAN is specialy designed to make noise prediction calculations to prevent noise nuisance.
