    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.

    Sound instrumentation for environmental noise monitoring

    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.

    Ambient air quality monitoring at airports

    To measure the ambient air quality at airports is a challenge. The monitoring site needs to be representative for background levels and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability. The OPSIS DOAS system provides the user with a fast system that gives high availability at low cost. The impact of aircraft take-offs and landings can easily be followed on-line. The OPSIS system can also monitor fugitive emissions from other sources at the airport.

    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.

    Sound instrumentation for measuring sound

    What is the difference between sound and noise? Clearly more than the loudness only. Although an aircraft is very noisy, a mosquito at night-time can be more than enough to spoil a good night`s sleep. Instead of looking at the loudness only as a criterion for the degree of noisiness, we shall simply regard noise as what it is - viz. unwanted sound.

  • Noise monitoring solutions for production testing

    The word `quality` is generally used in connection with expensive items and luxury goods. Nowadays, the quality of their product is what suppliers and sub-suppliers live by. Customers, world over, demand and expect it. In manufacturing, much effort has gone into `engineering in` quality by carefully optimising the design and production methods. However, a variety of manufacture and assembly faults often result in unacceptable noise and vibration levels in manufactured products. There is still only one method that makes absolutely sure that every item coming off the production line fulfils expectations. That method is production line testing, where every unit produced gets checked as part of its production cycle.

  • 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.

  • 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.

  • 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 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 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.

  • 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 electroacoustics

    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.
