Other FAQ

Are there any environments in which it is not safe to use ISOtunes products?

ISOtunes products do an excellent job of blocking outside noise. As such, they should NOT be used in environments where users need to be fully aware of their surroundings for personal safety reasons. For example, we do NOT recommend using them while driving a car or riding a motorcycle. Similarly, we do NOT recommend them for use when riding a bicycle outside. The user is solely responsible for ensuring that ISOtunes products are used ONLY in safe environments.

Are ISOtunes approved for use in my workplace?

Each workplace has its own rules and restrictions on what can or must be used to ensure prevention of hearing loss. For most facilities, the main requirement is that the Noise Reduction Rating for the devices is sufficient.

Simply ask your manager or company’s Safety Official to determine whether or not ISOtunes products are suitable for your workplace. And when using ISOtunes products, please abide by the rules established by your place of employment.

Contact us if you would like more information about getting ISOtunes approved for your workplace.

What is a Noise Reduction Rating?

ISOtunes and ISOtunes PRO are tested and approved in accordance with ANSI S3.19-1974 specifications. As such, they meet OSHA and NIOSH requirements to be used as hearing protectors in the workplace. When used as directed, ISOtunes offers a Noise Reduction Rating (NRR) of 26 dB and ISOtunes PRO offers an NRR of 27 dB.

An official Noise Reduction Rating (NRR) is a certification of the number of decibels a noise level can be reduced by the proper application of the device being tested. This rating is important because it allows consumers to choose devices that will provide adequate noise reduction given their normal activities and usage.


- The surrounding noise level measured at the ear is 90 dB.
- The NRR of ISOtunes is 26 dB.
- The noise level entering the ear is approximately equal to 64 dB.

Please note that the NRR is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise, such as gunfire.
