      Serenity DP+ electronic hearing protection

      Serenity DP+ is a dynamic (or 'active') hearing protection system that features level-dependent electronic sound reduction. It is an ideal choice for users who are regularly exposed to fluctuating levels of loud noise. Now featuring plus-level (+) technology for enhanced listening comfort.

      The system provides exactly the protection required by continually measuring the surrounding noise and adapting its attenuation (in-ear noise reduction) accordingly. This means excessive sound reduction is never an issue and you can remain fully aware of your surroundings, with the confidence to wear your protection all the time.

      With Phonak’s electronic hearing protection, dangerously loud sounds are instantaneously reduced to a safe in-ear level. This rapid-fire response even ensures that short and unexpected 'impulse noises', such as shots and crashes, are dampened the moment they occur.

      When surrounding noise levels return within a safe range, Serenity DP+'s attenuation is automatically reduced, allowing you to enjoy full ambient awareness, localize warning signals, and hold natural conversations. (This 'ambient' volume can even be increased if required).

      • Level-dependent electronic hearing protection
      • Instant protection against impulse noise
      • Full ambient awareness in quiet
      • Custom-molded eShells
      • SafetyMeter compatible

      Like other Serenity systems (except Classic), Serenity DP+ is fully modular. Simply click out your custom-molded eShells and click into another Serenity system.

    • eShells

      Phonak eShells

      ‘eShells’ are Phonak’s custom-molded in-ear shells. Offering the best hearing protection for full-time workers who operate in noisy environments, eShells are durable hollow molds made from clinical nylon.

      They are produced using a computerized 3D version of the user’s individual ear impression, which is taken beforehand by a hearing technician (a process that takes just 5 minutes).

      When a Serenity or Primero DPC system’s earJack is clicked into an eShell, the ear is instantly and fully sealed. Only sounds that have then been attenuated (reduced) by the user’s Phonak system reach the ear drum; protecting the user from dangerous noise throughout the day.

      • 100% individualized hearing protection
      • Perfect in-ear fit
      • Highly robust & machine washable
      • Quick and cost-efficient reproduction
      • Easy to maintain and assess using SafetyMeter

      Generic ear shells are also available. These one-size-fits-all versions are ideal for temporary or part-time use. Contact us for more details.
