Evaluation and Optimization of Hearing Devices in 3-D Complex Audio Environments

A methodical evaluation of novel sound changing principles in CE-labelled Sonova brand hearing instruments (e.g. Phonak hearing instruments) is intended to be conducted on hearing impaired participants. These sound changing principles are enabled by respective hearing instrument technologies and hearing instrument algorithms. The aim of the study is to investigate and assess strengths and weaknesses of these novel sound changing principles in terms of hearing performance to determine their application in hearing instruments (Phase of development). Both, objective laboratory measurements as well as subjective evaluations in real life environment will be carried out. This will be a controlled, single blinded and randomised active comparator clinical evaluation which will be conducted mono centric at the University Hospital of Zürich.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Adult normal hearing persons (minimum age: 18 years)
  • Healthy outer ear (without previous surgical procedures)
  • Ability to fill in a questionnaire conscientiously
  • Informed Consent as documented by signature

Exclusion criteria

  • Contraindications to the MD in this study, e.g. known hypersensitivity or allergy to the investigational product
  • Limited mobility and not in the position to attend weekly appointments
  • Limited ability to describe listening impressions/experiences and the use of the hearing aid
  • Inability to produce a reliable hearing test result
  • Massively limited dexterity
  • Known psychological problems
  • Known central hearing disorders

Treatment and study plan

several virtual 3-D complex audio environments

Procedure

The focus is a comparison of four virtual 3-D complex audio environments with regard to the sensitivity of hearing aid algorithms.

Primary outcomes

  1. Head movements measured with head tracker

    Time frame: 6 weeks

    The participant starts the acoustic stimulus, tries to identify the direction of the stimulus as precise as possible and validates the final position. This is interpreted as reaction time with regard to spatial quality in seconds [s].
