  • An Industrial Noise Map is Basic to Hearing Conservation

    An Industrial Noise Map Is Basic to Hearing Conservation In the U.S., OSHA has set regulations on worker noise exposure. The usual measurement method is to use a portable noise dosimeter attached to a worker that measures noise exposure as the person moves about the work area. However, this does nothing to identify the source and location of the noise. When conducing a noise survey, a noise ...

  • The Curious Divide between Conservation Science and IA

    Since returning to academia, I have been struck by a particular disjuncture between the biodiversity sciences and IA practice in my country, Namibia. Having worked across Africa, my suspicion is that it probably applies to the entire continent, perhaps even broader. Allow me to expand. I had my wildlife scientist hat on a few weeks ago at a southern African symposium on wildlife tracking and ...

  • I Need A Noise Dosimetry Survey. What Do I Do?

    Employees in noisy workplaces are at risk of permanent damage to their hearing. For a noisy workplace, establishing a Hearing Conservation Program is imperative to protecting both employee health and employer liability. Where to start? Sometimes, determining the appropriate type of protection for each employee can be tricky, because individual employees may have varying levels of exposure to ...

  • The Auditory & Non-Auditory Effects of Noise Pollution:An Occupational Health Study

    1. Introduction: The present study was planned as a prospective, longitudinal and panel-type of a study with the documentation of the health effects of noise exposure as its primary objective. Noise as a health hazard has been studied extensively in the last decade and a substantial amount of dose-response information on NIHL and its risk factors has been documented. However most of these studies ...


  • 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. ...

  • Our energy independence and job creation is not a partisan issue anywhere in the world

    I have some questions for what our country's principles were built from. How have jobs been created in the past? I don't remember it being the governments' responsibility to create jobs or pay for this. Aren't we a happier bunch when people are not on unemployment and gainfully occupied? Isn't it the responsibility of those who are in business to employee those locally? I got that impression. ...


  • Energy efficiency: a bubble or a vaccum

    No one much likes hearing their industry may be in a bubble. Bubbles burst and it hurts. We’re seeing that now in housing. So it’s understandable that clean energy companies aren’t exactly happy that economist Eric Janszen (itulip.com) says their industry may experience the next bubble. Apparently, clean energy is exhibiting bubble-like symptoms: It is the talk of the town, attracts investors ...

  • Congress feels no pain

    A big question often asked by energy analysts is: How high must energy prices be to motivate customers to change their behavior? We are beginning to think that the more perplexing matter is just how much do we pay before Congress reforms its behavior.Prices are plenty high enough to encourage customers to conserve. Driving is down and pursuit of efficiency is up. Federal lawmakers, however, can’t ...
