Hearing Protection with Situational Awareness Improves Workplace Safety
April 10, 2024 by Magnum Electronics

How Much Noise is Too Much?

Noise above 80dB can cause hearing loss over time. OSHA requires hearing protection when the 8-hour time-weighted average is 85 decibels or greater. You can map the noise level of your workplace with a free smartphone app like Sound Meter.

Sensear Allows Situational Awareness

Sensear SENS technology uses miniature mics to provide 360 degree situational awareness but instantly blocks harmful noise. SENS separates the background noise from voice to provide clearer voice communications. The result is workers can talk face-to-face without removing their muffs and hear normally when harmful noise is not present.

Wearing standard earplugs and headsets on the job protect your ears but increases the risk of accidents. Hearing protection is really temporary hearing loss according to Dr. Keith Darrow, and decreases situational awareness. Without the ability to hear warning sounds, employees feel less safe and often remove their protection.

Sensear Smart Headsets for 2-Way Radios

If you are searching for headsets or earplugs for your 2-way radios the SM1R headsets and SP1R earplugs include SENS 360 situational awareness technology. They use the radio battery to power the headset. If your radio needs a battery powered headset the SM1B series is available. Adapter cables are available for many popular radios for Motorola, Kenwood, Tait, Icom, BK Relm, and Hytera. Intrinsically-safe certified versions are available too.

SM1R Standard & IS Smart Headset Choices

Sensear SM1R Headset StylesThe SM1R series requires an adapter cable with your radio connector. The SM1RB001 includes a headband and provides 27dB NRR hearing protection. There is a neckband version (SM1RE001) with 24dB NRR and the SM1RH001 helmet mount with clips and 23 dB NRR.

If your radio has UL, CSA, or TIA label for intrinsically-safe operation in hazardous locations choose the SM1RISB1 headband, SM1RISE1 neckband, or SM1RISH1 helmet mount. 

These models have a red band on the headset and adapter cable. Add the appropriate intrinsically-safe certified adapter cable for your radio.

The SM1PB002 headband with 27db NRR, SM1PE002 neckband with 24 dB NRR, and SM1PH002 helmet with 23 dB NRR have rechargeable batteries with 20-24 hour operating time.
