Sensear Product Acronyms: Sensear uses a variety of product acronyms to designate specific features and functionalities in its headsets. Here's a breakdown:

Situational Awareness:

Situational awareness refers to the ability to remain aware of your surrounding environment while wearing hearing protection. Sensear’s headsets enhance this by allowing users to hear critical environmental sounds, alarms, and voices while blocking out harmful noise, ensuring safety and awareness in high-noise areas.

Noise Suppression:

Noise suppression technology reduces or eliminates background noise in high-noise environments. Sensear’s headsets use advanced algorithms to suppress dangerous noise levels while maintaining communication clarity, enabling safe and effective conversation in environments where traditional communication is impossible.

Intrinsically Safe:

Intrinsically safe equipment is designed to operate safely in hazardous environments where flammable gases, vapors, or dust may be present. These devices, including some Sensear headsets, are engineered to prevent the possibility of sparks or excessive heat, ensuring they won’t ignite dangerous substances, making them ideal for industries like oil and gas, mining, and chemical manufacturing.

Dual or Double Hearing Protection:

Traditional Dual or Double Hearing Protection involves the use of two types of hearing protection simultaneously, typically earplugs worn under earmuffs or a communication headset. This is required in extremely high- noise environments where noise levels exceed 110 dB(A) to provide enhanced protection against hearing damage. Sensear’s Dual Protection headsets integrate earplugs within the earmuffs, providing users extra protection without compromising communication and situational awareness.

Noise-Induced Hearing Loss (NIHL):

Noise-Induced Hearing Loss is a permanent form of hearing damage caused by prolonged exposure to high levels of noise, typically above 85 decibels. In occupational settings, workers in industries like manufacturing, construction, and mining are especially at risk. NIHL is preventable with proper hearing protection, such as Sensear’s advanced headsets.

Noise Reduction Rating (NRR):

Noise Reduction Rating (NRR) is a measurement used to indicate the effectiveness of hearing protection devices, expressed in decibels (dB). It shows how much noise a device can reduce in high-noise environments. For example, an NRR of 30 means that the device can reduce noise exposure by up to 30 dB(A). Sensear’s headsets offer NRRs ranging from 23-27 dB for standard headsets, providing substantial protection in high-noise environments while maintaining communication clarity. For environments with extreme noise levels, Sensear’s dual protection headsets offer an NRR of 36 dB, combining over-ear and in-ear protection for maximum noise reduction.

Single Number Rating (SNR):

Single Number Rating (SNR) is a European standard measurement that indicates the overall level of noise reduction a hearing protection device can provide, expressed in decibels (dB). SNR provides an easy-to-understand number to assess how much sound attenuation a device can offer in loud environments. For example, an SNR of 30 means that the device can reduce the average noise level by 30 dB across various frequencies. Sensear’s headsets offer reliable SNR values, delivering effective noise protection while ensuring clear communication. With SNR ratings that align closely with global standards, Sensear headsets provide robust hearing protection and intelligibility, even in extreme noise conditions.

Sound Level Conversion (SLC80):

Sound Level Conversion (SLC80) is an Australian and New Zealand standard measurement that represents the amount of noise reduction a hearing protection device can provide for 80% of users, expressed in decibels (dB). This rating is a conservative estimate, ensuring that most wearers achieve the expected level of protection in various noisy environments. For instance, an SLC80 rating of 30 dB means that 80% of users can expect a noise reduction of up to 30 dB. Sensear’s headsets deliver reliable SLC80 ratings, offering strong protection levels and clear communication in high-noise environments. With this rating, Sensear ensures effective noise reduction that meets diverse needs across industries, from manufacturing to heavy construction, enhancing both safety and communication.

Volume Limiter:

A volume limiter is a feature in hearing protection devices that restricts the maximum audio output to a safe level to prevent users from accidentally listening at volumes that could cause hearing damage. Sensear’s headsets limit noise to 82 dB(A) to protect users from high levels of sound, even when using communication features.

Short-Range:

Short-range communication refers to wireless, headset-to-headset communication over limited distances without the need for external devices such as radios or cell phones. Sensear headsets utilize FM frequencies to facilitate this short- range communication in small work groups up to 150 ft, enabling efficient and effective coordination without relying on additional communication equipment.

IP Rating (Ingress Protection Rating):

The IP Rating (Ingress Protection Rating) is an international standard that defines a product's resistance to dust and water. It is composed of two numbers: the first indicates protection against solids like dust, and the second indicates protection against liquids like water. Sensear headsets are rated IP54, meaning they are protected against limited dust ingress and water spray from any direction. Additionally, Sensear's noise-canceling boom microphones feature a higher IP67 rating, offering full protection against dust and immersion in water up to a certain depth, making them highly durable in harsh working environments.
