    Sound instrumentation for calibration

    Unfortunately, the word calibration has ended up having two meanings; viz. to describe the use of a sound calibrator in connection with a measurement and to describe periodic verification which is carried out in a Calibration Laboratory.

  • Noise monitoring solutions for sound intensity mapping

    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.

    Sound level meters & Noise dosimeters for Environmental noise monitoring industry

    Environmental Noise is one of the fastest growing areas of noise monitoring, mapping and control. The EU has introduced a number of Directives aimed at increasing the level of information about Environmental Noise across the EU. In 1996, data from the EU Green Paper on Future Noise Policy estimated that around 20% of the EU`s population, or close to 80 million people, suffer from noise levels that experts consider to be unacceptable. Most of these people become annoyed and suffer from sleep deprivation, which experts fear will lead to adverse health effects. An additional 170 million citizens are now living in so-called "grey areas" where the noise levels cause serious annoyance during the daytime.

  • Noise monitoring solutions for urban noise

    The sounds in a city are central to our quality of life. Constant exposure to noise effects both our physical and psychological health, and our ability to learn and communicate.

  • Noise monitoring solutions for material testing

    With today`s growing focus on noise control issues and the emergence of sound quality as an important aspect of product design, acoustic material testing is becoming increasingly relevant to engineers, designers and manufacturers from a broad range of industries. Acoustic material testing is the process by which the acoustic characteristics of materials are determined in terms of absorption, reflection, impedance, and admittance, including transmission loss.

  • Pulsar noise testing equipment for vehicle noise measurement industry

    In a world where there is a drive for everything to be quieter, vehicle noise measurement and control is a growing application. If measurements need to be made to ISO 5130:2007, which is an internationally recognised standard for vehicle exhaust noise testing, a more detailed measurement needs to be made. ISO 5130:2007 requires three consecutive measurements to ensure repeatability. These measurements are taken at a specified engine speed, or RPM, and the maximum sound level produced during the test is taken.

  • Noise monitoring solutions for environmental noise and vibration

    Environmental noise is unwanted sound and vibration coming from a plethora of sources, among them industrial plants, road and rail traffic, construction work, and aircraft. Add to these sports events, shooting ranges, leisure parks, etc, and you have noise from many different sources, each with different characteristics and posing specific problems for the professionals who have to assess them. The way the problems are dealt with differs immensely from country to country and is very much dependent on culture, economy and politics. We offer solutions to cover all demands from level checks to in-depth analysis, from measurement or prediction, to post-processing and reporting.

  • Low frequency noise analysis using XL2

    The Data Explorer PC software for the XL2 Sound Level Meter now includes a series of professional tools for detailed analysis of low-frequency noise (LFN). The graphical representation of time varying frequency components offers an efficient process for identifying the presence and level of LFN. Also the associated high quality audio recording supports further correlation with the objective measurement data. The new features are particularly useful in the calculation of immission levels which is defined as the cumulative noise energy to which an individual is exposed over time. Exposure to low-frequency noise over extended periods can lead to a range of health problems including cardio vascular disease, insomnia and depression. The sources of low frequency noise can often be attributed to electricity sub stations, chiller plants and incinerators with continuous noise at frequencies below 200 Hz. XL2 Sound Level Meter records all Data Measuring LFN requires a class 1 sound level meter

  • Noise and vibration problem solutions for building & construction sector

    Approved Document E of The Building Regulations (2003 Edition) is the document setting out the requirements for sound insulation in buildings. It contains a requirement that organisations carrying out sound insulation testing should be third party accredited in order to demonstrate their competence to carry out such work. We are registered under The Association of Noise Consultants scheme as a testing organisation.
