Do You Need a New Audiometer?

How is the old audiometer working these days?  Is it time for an upgrade? Speaking of upgrades, take a look at the Tremetrics RA 660 Audiometer-

This device is a combination:

Audiometer

Bio-Acoustic Simulator

HearCon Software

Optional – External Type 2 Microphone, (no booth, no problem)

This audiometer sells for $4,495.00. Add a second audiometer to the same location for $2,495.00.  Don’t have a booth, add the external Type 2 microphone for background noise monitoring for $1,195.00. The audiometer has the option to pause the test if the background noise levels exceed the allowable levels per the OSHA Standard.

With HearCon software (and if you already have Workplace Applications or HT Pro software), this audiometer works by showing the baseline and the live test results on the screen as the person is taking the test.

Tired of giving the same test instructions? Set the instructions to be presented to the individual prior to the start of testing under the headset, oh and you can set the instructions to be given in the language of your choice.

Are you testing in a mobile environment?  This audiometer can be used in a mobile environment with separate booths, or a single testing room with multiple audiometer stations.

Your Skull Shapes Your Hearing

Uncategorized

Scientific American By Christopher Intagliata on October 17, 2019

The resonant properties of your skull can amplify some frequencies and dampen others—and, in some cases, affect your hearing. Christopher Intagliata reports. 

Certain concert venues, like Boston’s Symphony Hall, are known to beautifully reflect the sounds of an orchestra. It turns out there’s a similar process at play in your cochlea, deep inside your ear—where a tiny bony cavity houses the organ that allows you to hear.

“It’s like its own tiny little acoustics chamber, if you will. So anything and everything you hear is going into our ear and then going into this little bony chamber.”

Mike Gordon, a psychologist at William Paterson University in New Jersey. But while studying this process, he also found there’s actually a lot of variability in the way people hear. Some frequencies can appear tens of decibels louder or quieter than average—based on the resonant properties of a person’s skull.

13-year-old publishes research paper showing hand dryers are too loud

Uncategorized

Article by Meghan Holohan, MSN Today

When Nora Keegan would visit a restroom and use a hand dryer, she often thought it sounded too loud. Sometimes she’d notice other children stuffing their fingers in their ears to quiet the roar of the dryer while exasperated parents looked worried that their child was too sensitive. That’s when Nora, then 9, decided to measure sound coming from the hand dryers for a science fair project.

Nearly four years later, the Canadian journal Pediatrics & Child Health published a paper she wrote about the findings showing that Nora’s instinct was right.

“Sometimes after using hand dryers my ears would start ringing,” the 13 year old, soon-to-be ninth grader from Calgary, Canada, told TODAY Parents. “I started wondering that maybe (hand dryers) are too loud for our ears.”

Noise Induced Hearing Loss

Noise-Induced Hearing Loss
Act, before the damage is done
Exposure to harmful noise can happen at any age. People of all ages,
including children, teens, young adults, and older people, can develop
NIHL. Based on a 2011-2012 CDC study involving hearing tests and
interviews with participants, at least 10 million adults (6%) in the U.S.
under age 70 – and perhaps as many as 40 million adults (24%) – have
features of their hearing test that suggest hearing loss in one or both earsfrom exposure to loud noise.
Are you too late?
Tim Turney discusses the long-lasting impact this condition can have
and how employees must put monitoring processes in place to help
identify the issue in our latest news article…
