SINGLE Booth RE-125 (Theirs) vs.

GROUP Test Booth RM-183 (Ours)

According to Minnesota Pollution Control – A Guide to Noise Control in Minnesota – Page 9

“The human ear can usually tell the difference when sound changes by 3 dBA and a 5 dBA change is clearly noticeable. Because of how the logarithmic scale functions in compressing the measurements associated with sounds, an increase of 10 dBA (see above – 2000 HZ) sounds twice as loud.”

Almost every mobile medical provider that performs occupational audiometry uses Benson CCA-200 audiometers. Med Compass also utilizes the Benson BAS-200 SLM Bio-Acoustic Simulator in each test booth. Why?

The BAS-200 SLM will not allow the hearing test to be completed unless the OSHA requirements for background noise are met. If a loud noise interrupts the test while the tones are presented to the employee; the result is not logged and the tone is presented again.

BENSON CCA-200 AUDIOMETER – A test subject must correctly get 2 out of 3 consecutive responses at the same level. The same tone could be presented up to 21 times throughout the test to be accurate. We have been testing on the tarmac at the Minneapolis-St. Paul Airport for years.

In Summary

Med Compass utilizes a thicker wall booth for testing. According to acousticalsolutons.com, “What stops sound then? Heavy things. Layers of heavy things that are air tight.” The competition says they overcome this deficiency by adding insulation to the walls of the trailer. “FOAM DOES NOT STOP SOUND FROM GOING THROUGH WALLS!” Ask them what they use for insulation; if it isn’t a significant amount of steel or lead, it won’t work!

At the all important 2000HZ frequency, our walls are twice as quiet as the single wall booth.

Med Compass uses the Benson CCA-200 Audiometers and the BAS-200 SLM. Any noise interrupting the test will not affect the test results. See above.

To ensure the best results; the booth is only a small part of the solution. It’s the people, their process, and their competency. Our decades of experience make Med Compass the Sound Choice!
