简要总结

The goal of this interventional study is to evaluate the clinical performance and sound quality of the Osia 3 Sound Processor and to demonstrate its superiority compared with the Osia 2 Sound Processor in adults with mixed hearing loss, conductive hearing loss, or single-sided deafness.

The main questions this study aims to answer are:

  • Do the findings confirm the clinical performance of the Osia 3 Sound Processor?
  • Is the Osia 3 Sound Processor superior compared to the Osia 2 Sound Processor?

Participants will:

  • Undergo speech performance testing in both quiet and noisy environments
  • Provide ratings for a self-reported questionnaire

入选标准

  • Implanted with a Cochlear Osia Implant (OSI100, OSI200, OSI300)
  • Conductive or mixed hearing loss in the implanted ear. Bone conduction thresholds up to 65 dB HL (up to 40 dB HL at 0.5 kHz, up to 55 dB HL at 1kHz and up to 65 dB HL at 2 and 4 kHz) or Single-Sided Deafness in the implanted ear. The pure tone average air conduction hearing thresholds of the hearing ear should be better than or equal to 20 dB HL (measured at 0.5, 1, 2 and, 3 kHz).
  • Aged 18 years or older, at time of consent.
  • Minimum experience of 1 month with the Osia 2 Sound Processor.
  • Fluent speaker in the language used to assess speech perception performance.
  • Willing and able to provide written informed consent.

排除标准

  • Ongoing infection at or around the sound processor area.
  • Bilaterally implanted with a Cochlear Osia Implant.
  • Unable or unwilling to comply with the requirements of the clinical investigation as determined by the Investigator.
  • Use of ototoxic drugs that could be harmful to the hearing, as judged by the investigator.
  • Investigator site personnel directly affiliated with this study and/or their immediate families; immediate family is defined as a spouse, parent, child, or sibling.
  • Cochlear employees or employees of Contract Research Organisations or contractors engaged by Cochlear for the purposes of this investigation.
  • Current participation, or participation in another interventional clinical study/trial in the past 30 days, involving an investigational drug or device (unless the other investigation was/is a Cochlear sponsored investigation and determined by the investigator or Sponsor to not impact this investigation).

结局指标

主要结局

Mean difference in speech reception threshold in noise with the Osia 3 Sound Processor, 1-2 weeks after fitting compared to the unaided condition at baseline

时间窗: At Baseline (Day 0), Visit 1 (7-14 days after Baseline), and Visit 2 (7-14 days after Visit 1)

Speech perception in noise will be assessed using the Australian Speech Test in Noise (AuSTIN) at the Australian sites and the Bamford-Kowal-Bench Speech-In-Noise (BKB-SIN) test at the US site. The AuSTIN uses BKB-SIN like target sentences presented in noise and comprises of 80 lists of 20 sentences each. The BKB-SIN test contains 18 list pairs of sentences, each containing 3-4 key words, presented at 65 dB SPL with adaptive noise levels. Both tests aim to determine the signal-to-noise ratio (SNR) at which 50% of the key words are correctly repeated. For the unaided and aided measurements, speech performance in noise will be measured with speech and noise presented from a front speaker, positioned at 1 m from the subject.

  • Mean difference in the four-frequency sound field threshold average (PTA4, mean of sound field thresholds at 0.5, 1, 2, and 4 kHz) with the Osia 3 Sound Processor, 1-2 weeks after fitting compared to the unaided condition at baseline(At Baseline (Day 0), Visit 1 (7-14 days after Baseline), and Visit 2 (7-14 days after Visit 1))
  • Mean difference in speech perception in noise with the Osia 3 Sound Processor compared with the Osia 2 Sound Processor measured at a fixed signal-to-noise ratio (SNR) of 0 dB SNR, 1-2 weeks after fitting(At Visit 1 (7-14 days after Baseline) and Visit 2 (7-14 days after Visit 1))
  • Mean difference in speech perception in noise with the Osia 3 Sound Processor compared with the Osia 2 Sound Processor measured at a fixed signal-to-noise ratio (SNR) of +5 dB SNR, 1-2 weeks after fitting(At Visit 1 (7-14 days after Baseline) and Visit 2 (7-14 days after Visit 1))
  • Mean difference in the Speech Spatial and Qualities of Hearing Scale (SSQ-12) global score with the Osia 3 Sound Processor compared with the Osia 2 Sound Processor, 1-2 weeks after fitting(At Visit 1 (7-14 days after Baseline) and Visit 2 (7-14 days after Visit 1))
  • Mean difference in the word recognition score in quiet with the Osia 3 Sound Processor compared with the Osia 2 Sound Processor measured at 50 dB SPL, 1-2 weeks after fitting(At Visit 1 (7-14 days after Baseline) and Visit 2 (7-14 days after Visit 1))
  • Mean difference in the word recognition score in quiet with the Osia 3 Sound Processor compared with the Osia 2 Sound Processor measured at 65 dB SPL, 1-2 weeks after fitting(At Visit 1 (7-14 days after Baseline) and Visit 2 (7-14 days after Visit 1))
  • Mean difference in speech reception threshold in noise with the Osia 3 Sound Processor compared with the Osia 2 Sound Processor, 1-2 weeks after fitting(At Visit 1 (7-14 days after Baseline) and Visit 2 (7-14 days after Visit 1))
