Your Nuraphone has been designed and tested with the strictest of consideration for safety, but please note: exposure to any loud noise at or above 85 Decibels (dB) (approximately the same volume of a food blender) can cause gradual hearing loss.
We recommend, due to the clarity and sound isolation of the Nuraphone, that you will not need to listen to your music as loudly as with many conventional headphone products.
However, please adhere to the safety instructions below and use your Nuraphone responsibly, particularly with regard to the level of Immersion.
| Sound |
Noise Level |
Effect |
| Rustling leaves | 20dB | Just audible |
| Quiet office | 60dB | Comfortable hearing levels are under 60 dB |
| Average city traffic | 80 dB |
Annoying; interferes with conversation; constant exposure may cause damage |
| Lawnmower, food blender, recreational vehicles, TV | 80-90dB | Annoying; interferes with conversation; constant exposure may cause damage |
| Symphony orchestra, power saw (chainsaw), pneumatic drill, jackhammer | 110dB | Regular exposure to sound over 100 dB for more than one minute risks permanent hearing loss. |
| Concert | 110-140dB | Threshold of pain begins around 125 dB |
More information is available via the National Institute on Deafness and Other Communication Disorders.
Monitor your use. Hearing loss is a function of loudness versus time. The louder it is, the less time you can be exposed to it. The softer the volume, the longer you can listen. For example, 8 hours at 85 dB causes as much damage as 4 hours at 88 dB, 2 hours at 91 dB, or just 15 minutes at 100 dB.
Do not listen to music at a high volume for any extended period.
Do not listen to music in the ‘front row’ level of Immersion at high volume for any extended period.
Only use your Nuraphone whilst the volume on your device is set at a comfortable, moderate level.
Use caution and follow applicable laws regarding mobile phone and headphone use if using the Nuraphone for phone calls while driving. Some jurisdictions impose specific limitations such as single earpiece use while driving.
Be aware that sounds that you may rely on as reminders or warnings (i.e. alarms, message tones, and incoming calls) may vary while using your Nuraphone.
If you experience a warming sensation or loss of hearing, remove your Nuraphone immediately.
If your Nuraphone emits a loud or unusual noise, do not use it and contact our Customer Experience Experts immediately.
Due to the noise isolating Inova™ technology, do not use the Nuraphone any time where an inability to hear may present a danger to yourself or others. For example, while driving, riding a bicycle, a construction site, or when you are in or near traffic.
Charging your Nuraphone must only be done with certified Nura cables.
Charging your Nuraphone should be done only in accordance with the instructions in this user guide.
