Custom-Fitted Hearing Protection & Communication Enhancement

All Sonomax Hearing Protectors are made from soft hypoallergenic silicone and shaped to your unique ear print forming an acoustic seal and without friction points so they can be worn for prolonged periods of time. Discomfort is a main factor that reduces the effectiveness of hearing protectors.








Sonomax™ Self-Fit Accessories

Sonomax is the premier custom molded, measured and calibrated hearing protection system that is tailored to each individual ear. It provides measurable hearing protection according to the noise exposure levels of each individual at their workplace.
Just like finger prints, the external and internal features of ears are different for each individual. Unlike foam plugs, no ear cavity is the shape of a cylinder.

Sonomax Hearing Protection is custom moulded for an exact fit in each ear, forming a perfect acoustic seal. It also ensures no pressure points between the shape of the plug and the ear canal, giving maximum comfort and no irritation. The internal form of the plug means that it won’t interfere with the use of other PPE.
When Sonomax hearing protection has been fitted, our SonoPass software driven process confirms that an acoustic seal has formed. Then it measures the personal attenuation level in each ear, calibrates the required level of sound attenuation, instructs the testing operator on the most appropriate filter to ensure a safe sound level for each ear and records the results. At the end of the process a formal report is generated which details the hearing protection provided for each ear for every individual.

omomax Hearing Protection can be coupled with communications devices to enable staff to hear communications clearly when working in extreme environments.

Sonomax™ Self-Fit Accessories

Sonomax offers functional accessories that are compatible with our hearing protectors. This line of enhancement accessories allows users to turn their Sonomax Self-Fit Hearing Protectors into an advanced protection device.
Noisy environments make it difficult for a person to hear and be heard. The use of communication devices such as two-way radios in these environments further decreases the chance that a clear message can be sent or received. Loud ambient noise is not only inconvenient, it is also dangerous. Sonomax offers integrated earpiece solutions that are plug and play with multiple radio systems.

The Sonomax Self-Fit hearing protection faceplate was developed to support all third party acoustic tube radio solutions. With the help of our SF Communication Elbow you can fit any acoustic tube style communication device to our earpiece.

Model No. HPD-V5-COMM

It consists of a communication set with a built-in compressor-limiter that amplifies quiet conversations and attenuates sounds that are too loud. This requires the purchase of any Sonomax Self-Fit filtered models (yellow, red or brown) in addition to the SF Communication Elbow.
Sonomax recommends the continued use of lubricant for ease of insertion and to ensure an optimal fit for the best attenuation. The lubricant can also be used to maintain cleanliness and longevity of the hearing protector.
