Phonak Serenity Choice reusable ear-plugs: Sleep

Serenity Choice: High-end hearing protection from Phonak.  

Serenity Choice™ Sleep is reusable, universal-fit hearing protection; ideal to use:

• To reduce the noise of a snoring partner - sounds from a moderate snorer can reach 50-60 dB whilst severe snoring noise can hit 90 dB...to put that in perspective; a car horn is around 90 dB! 
• In noisy hotels – reduces noise from lifts, revellers, kitchen noise, etc.
• To reduce street noise 

Serenity Choice™ Sleep reduces the sound level by 24dB, eliminating or reducing sound to a non-intrusive level.

Sleeping with ear tips may take a little getting used to, as it can sound unnaturally quiet for the first night; but after that you’ll probably wonder why you didn’t use them earlier!

Key features:

• Superior filter technology – Best in class acoustic filters for best acoustical performance. 
• Hypoallergenic material – medical grade TPE (ThermoPlastic Elastomer) is used for the eartips - TPE has some antibacterial properties, unlike silicone from which most tips are manufactured.
  
• Ventilation / Hygiene – the patented filter technology allows situational awareness and communication. Natural ear ventilation is supported which helps prevent moisture build up. This reduces the ‘hot ear’ sensation in the ear canal often found with other foam/silicone plugs. 
• 3 different ear tip sizes (S, M, L) to ensure a perfect fit for everyone.
• Washable with warm water - leave to dry completely before re-use

Information on NRR / SNR values provided: 

NRR: The NRR (noise reduction rating) is a method which attempts to describe a hearing protector based on how much the overall noise level is reduced by the hearing protector. The NRR as a clinical evaluation theoretically provides an estimate of the protection of a given device. The reasons for rating each hearing protector involve OSHA and EPA requirements for product safety and reliability. The rating enables the end user to assess the product 's attenuation abilities for noise in their own given work environment.  

SNR: The SNR (single number rating) is the system within the European Union to indicate the amount of protection offered by a correctly fitted hearing protection device
