Noise Pollution Applications

  • Indoor air quality (IAQ)

    Indoor Air Quality (IAQ) refers to the effects on human health of various factors that are properties or constituents of the air we breathe and generally indoors. Very briefly, we can say that a series of events led to the finding that many chemical or biological substances can be inhaled which can cause various health problems which start as simple disorders but lead to serious illnesses. Of similar importance are several natural parameters of the so-called `interior environment`.

  • Noise monitoring for airport noise

    Air traffic is the source of several forms of disturbance to the surrounding area, including, in particular, noise pollution. Local residents in the vicinity of an airport are the most severely affected and are very conscious of the aircrafts` flight paths and the impact on their day-to-day living conditions.

  • For Sports Facilities

    Troy Acoustics and its personnel have been involved in the Broadcasting, Movie and Recording industries for well over thirty years. Troy Acoustics has designed and installed acoustical treatments for dozens of facilities, for both new and updating purposes. The Troy System products, designs and installation techniques have provided quality, noise free, environments for all types of facilities where original programming is produced, enhanced or modified.

  • Wind farm noise monitoring

    Wind energy is a renewable energy source that is being harnessed globally to reduce our dependence on fossil fuels and the associated impact on our environment. However, the environmental impact of the turbine noise and the blade pass noise is a concern that is carefully monitored and generally regulated. It is very important to be able to acquire accurate acoustical data for analysis, noise impact predictions, and regulatory compliance. Effective noise monitoring is a very valuable tool to manage a wind farm’s relationship with the community and with the local regulatory organizations.

  • Noise monitoring for airports

    Airports, small and large, use noise and operations monitoring systems to reduce the noise of flight operations in the surrounding community.  Noise monitoring is generally used to evaluate noise abatement programs and to develop aircraft departure and arrival procedures that minimize the impact of aircraft noise based upon altitude, flight path, and time of day.  Noise monitoring is linked with radar tracking so that specific aircraft can be identified when noise limits are exceeded and so operational requirements can be enforced.
    Larson Davis provides noise monitoring systems to airports, consultants, and system integrators with the technology and support to make a successful program.

  • Noise monitoring for railways and trains

    Controlling and monitoring railway and train noise in residential and urban areas is a critical function of a railway. The noise generated can be dependent upon the engine, rail cars, rail construction, train speed, and the horn. Modern high speed trains have also created new levels of high frequency noise that create an acoustic disturbance that sounds like an aircraft going by.

  • Noise monitoring for industrial sites

    Industrial noise generated from plants, mills, refineries, shipping docks, utilities, and more, impact the quality of the surrounding community.  By controlling and monitoring this noise a community and industry can establish a working relationship that will benefit all.  An effective noise monitoring program will allow an industrial site to understand the noise sources and time periods that are causing concerns and then develop a plan for mitigation.

  • Noise monitoring for the petrochemical industry

    Many industrial operations take place over lengthy time periods and operations often continue 24 hours a day.  By implementing a 24 hour noise monitoring system, with real-time communication and alert notification, a plant can demonstrate to the community and regulatory agencies that they are sensitive to the community and prepared to root-cause and correct any problems that may arise.

    Noise monitoring solutions for sound power

    Noise emission values are increasingly becoming marketable items for machines, equipment and appliances - low noise emissions directly relate to lower noise exposure for product users and bystanders. Retail customers, both private and corporate, appreciate this relationship and are, therefore, more aware of noise emission declarations on goods when deciding their purchases.

    Noise monitoring solutions for Pass-by noise testing

    Traditional Field Pass-by measurements are still the only way to certify a vehicle for exterior noise emission during operation, but Indoor Pass-by provides an extremely powerful and repeatable method of troubleshooting exterior vehicle noise in the controlled environment ofan anechoic chamber.

    Sound Instrumentation for Industrial Hygiene

    Industrial hygiene is separated into two main applications - Noise at Work and Human Vibration. Norsonic has during the past year expanded the product portfolio to cover both applications. By close cooperation with our customers and health and safety research institutes we have designed a carefully balanced selection of measuring tools and application software that covers both the vibration and noise domain.

    Fence line monitoring around an industrial site or airport

    Monitoring the potential escape of pollutant gases from industrial sites or from airports can be difficult to achieve due to changing weather conditions, which may require a large number of monitoring stations downwind of the escapes.

    2-Channel sound insulation for building acoustics

    Façade sound insulation is measured like sound insulation between rooms, except that one `room` is actually open space. The sound level is measured inside the receiving room and outside the façade of the building. The level difference is then corrected for the influence of the reverberation time and background noise level in the receiving room. Finally a single-number index is calculated by averaging over all the frequency bands. A loudspeaker source can be used for the measurement, giving a choice of sound incidence angle. But in practice, placing the loudspeaker and getting a high enough sound level can be difficult.

  • 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.
