  • Manage the rise in deafness claims with Pulsar Instruments

    The recent reports in the press about insurance groups complaining of a sharp rise in claims from employees seeking compensation for hearing problems have highlighted the real risks of noise induced hearing loss and the importance of protecting employees in the workplace. Although employees are protected by Law, noise induced hearing loss is often ignored. And once hearing loss has occurred, it ...

  • How listening to the ocean can help reveal environmental damage

    In 2013, Katherine Indeck listened to recordings of sounds made in a channel between the Gulf of Mexico and Tampa Bay, Florida. Some of the audio files had been collected in 2005 during an unusually severe red tide, a bloom of toxic algae that killed fish, dolphins and sea turtles. Other recordings were made after the ecosystem began to recover. During the recovery years, Indeck could hear sounds ...

  • Hol’z dir! Sustainable briquette manufacture in the Augustinuswerk Jessen case study

    Since only very recently the Augustinuswerk in Jessen has been producing wood briquettes under its own brand name of “Hol’z dir” in a separate workshop for the handicapped. Only machines from shredder specialist WEIMA are used for production, their own production facilities being only a few kilometres away in Großnaundorf. It is very busy here. Every day 3,000 wood ...

  • Brüel & Kjær accelerometers - 65 years of excellence

    The Thirties Already before the two young engineers Per V. Brüel and Viggo Kjær graduated as Masters of Electrical Engineering in 1939, they had decided to start a company together. However, they felt it was necessary to learn more and get some practical experience before actually going ahead, so P.V. Brüel became assistant to professor P.O. Pedersen in the newly created ...

  • Innova`s race against time; the sonic mystery

    What began as a puzzling mystery in the semi-arid scrub-land of Colorado, ended as a race against time for the acoustic specialists of INNOVA (formerly ATCO Noise Management). The Olathe Compression Station, operated by Kinder Morgan’s TransColorado Gas Transmission, is located on a plateau in isolated, canyon-cut Colorado countryside, three km from the nearest ...

  • Ocean science for sustainable development: Facts and figures

    Sarah Grimes explores why we need good ocean monitoring, how to get it, and why it still fails Small Island Developing States. Oceans are a critically important component of the Earth system, supporting ecosystem and human health. They regulate the weather and climate; are essential for producing freshwater; and soak up ...

  • Engineers torque technology to medics

    Medical experts and sports scientists are becoming increasingly reliant on engineers as their disciplines become more and more technical. Mark Ingham looks at some of the projects his company, Sensor Technology, has helped behind the scenes. Like most rugby players I took my knees for granted until the day a twisting fall resulted in a torn anterior cruciate ligament. Fortunately these days it ...

  • Noise in the Animal Shelter Environment: Building Design and the Effects of Daily Noise Exposure

    Sound levels in animal shelters regularly exceed 100 dB. Noise is a physical stressor on animals that can lead to behavioral, physiological and anatomical responses. There are currently no policies regulating noise levels in dog kennels. The objective of this study was to evaluate the noise levels dogs are exposed to in an animal shelter on a continuous basis and to determine the need, if any. ...

  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...
