Noise monitoring solutions for electroacoustics

by Brüel & Kjær Sound & Vibration Measurement A/S     based in Nærum, DENMARK

Manufacturers of electroacoustic equipment such as loudspeakers, microphones, telephones, headsets, hearing aids, hydrophones, etc., have, for many years, successfully developed new innovative acoustical designs and introduced these into the market in the form of high-quality products.

Sound Instrumentation for Environmental Noise Monitoring

by Norsonic AS     based in Lierskogen, NORWAY

State of the art noise monitoring systems; Modern noise monitoring systems offer a wide range of advanced features and come with software that can analyze and structure long term measurements data efficiently.  A complete noise monitoring system consists of one or more noise monitoring terminals, a noise server and work stations for presentation, post processing and reporting.

Water Monitoring and Flow Measurement Systems for Hydrology

by HydroVision GmbH     based in Kaufbeuren, GERMANY

In recent years acoustic flow measurement and flow metering has established itself as the standard method for measurement in many hydrological stations but is also used as the basis for various applications, for example for flood protection and flood forecasting. Ultrasonic flow meters are also used in hydro-engineering constructions. With this almost contact free technology data can be recorded continuously and it provides 24/7 monitoring. Such flow monitoring is particularly important in waterways used for shipping, transportation, irrigation, drainage and for cooling water extraction of power plants. A further important use of transit-time open channel flow meters is the transportation of water used for the supply of drinking water. Here the focus lies on detecting the flow rate of water loss at an early stage as it is sometimes difficult to detect small leakages.

Noise monitoring solutions for sound intensity mapping

by Brüel & Kjær Sound & Vibration Measurement A/S     based in Nærum, DENMARK

Sound Intensity is the measure of acoustic energy passing through a unit area. By integrating over a surface enclosing an object under test, you can calculate the object`s sound power. This can be done regardless of background noise, allowing convenient, in situ measurements of sound power. Other advantages of sound intensity measurements include the ability to determine the directionality of sound, and to quickly localise noise `hot spots`. Mapping software takes this a stage further by providing you with a contour map of noise levels to provide intuitive documentation of noise problems.

Noise monitoring solutions for room acoustics

by Brüel & Kjær Sound & Vibration Measurement A/S     based in Nærum, DENMARK

Room Acoustics concerns the way sound is created, propagated, perceived, measured and modelled inside enclosures. Enclosures can be dwellings, offices, workshops, factory halls, lecture rooms, auditoria, concert halls, transportation terminals, etc. Reverberation Time is the single most important parameter used to describe Room Acoustics, but in addition, parameters describing music quality and speech inteligibility are important.

Pulsar noise testing equipment for construction industry

by Pulsar Instruments plc     based in Filey, UNITED KINGDOM

The construction sector and its wide range of associated activities are very varied and from a noise monitoring perspective offer many unique challenges. However, Pulsar Instruments have a solution; a construction Pulsar noise meter with the ability to effectively assess the following two key categories; Noise at Work (potential for noise induced hearing loss due to long term exposure to noisy activities). Environmental Noise (the potential to cause annoyance to surrounding areas or buildings during site work).

Sound Instrumentation for Building Acoustics

by Norsonic AS     based in Lierskogen, NORWAY

The field of building acoustics consists of two parts; Room Acoustics which deals with sound propagation in a room and Building Acoustics, which deals with sound propagation between rooms. Typically, room acoustics is related to the quality of sound, e.g. concert hall acoustics, while building acoustics is more related to unwanted sound, i.e. when you want to hear as little as possible of what is going on in adjacent rooms. From a measurement technology point of view, the two have a lot in common which shall be outlined here.
