How SM1P-ExDP Can Help Protect Your Hearing in Load Working Environment

Noise is one of the most common occupational hazards that workers face in various industries. Exposure to excessive noise can cause permanent hearing loss, tinnitus, stress, fatigue, and reduced concentration. To prevent noise-induced hearing damage, employers and workers should take appropriate measures to reduce noise exposure and protect their hearing. However, in some situations, it may not be possible or sufficient to control the noise by technical and organisational means. In such cases, workers should use hearing protection devices (HPDs) as a supplementary measure or a short-term solution while other methods of noise control are being developed.

What is SM1P-ExDP?

SM1P-ExDP is a smart extreme noise headset that provides dual hearing protection and communication capabilities for workers in hazardous locations that require ATEX and IECEx certification. It is based on the existing SM1P-Ex headset and incorporates Sensear’s unique dual protection feature, which combines earmuffs and earplugs to provide a higher level of noise reduction for exposures above 95 dB(A). The SM1P-ExDP headset also enables high-noise two-way radio, Bluetooth®, headset-to-headset, and face-to-face communication in explosive environments such as explosive chemicals and fuels as well as combustible powders. The new cable connection at the ear cup allows users to use it as a wired headset along with Bluetooth® and Short-Range or unplug the cable and use it as a completely wireless headset via Bluetooth® and Short-Range.

How can SM1P-ExDP help protect your hearing?

The SM1P-ExDP headset can help protect your hearing in load working environments by:

• Providing dual hearing protection with up to 38 dB SNR (single number rating) for exposures above 95 dB(A)
• Limiting the ‘in-ear’ noise exposure to 82 dB(A) [programmable] by using Sensear’s SENS® technology
• Enhancing speech while suppressing background noise to a safe level
• Retaining 360° situational awareness by allowing users to hear ambient sounds and warning signals
• Reducing the need to remove the hearing protection for communication purposes

How can SM1P-ExDP help improve your communication?

The SM1P-ExDP headset can help improve your communication in load working environments by:

• Allowing users to connect to intrinsically safe two-way radios via Bluetooth® or via a removable wired connection
• Allowing users to connect to intrinsically safe mobile devices (HFP, HSP, and A2DP profiles) via Bluetooth®
• Allowing users to communicate with other headset users (up to 50 meters / 150 feet range) via Short-Range
• Allowing users to talk ‘face-to-face’ with SENS® mode (< 95dB)
• Providing a noise-canceling boom microphone that is VOX capable
