Summary

Users are generally satisfied with hearing aids (HA), with most able to use and manipulate them. However, satisfaction varied by HA type, with analogue hearing aids (A-HA) preferred over digital signal processing aids (DSP-HA).

Area of Science:

  • Audiology
  • Biomedical Engineering
  • Public Health

Background:

  • Hearing aid (HA) technology has advanced significantly, encompassing analogue (A-HA), programmable (P-HA), and digital signal processing aids (DSP-HA).
  • Understanding user satisfaction and ease of manipulation is crucial for effective hearing rehabilitation and technology adoption.

Purpose of the Study:

  • To evaluate user satisfaction and manipulation success with hearing aids (HA).
  • To compare these parameters across analogue (A-HA), programmable (P-HA), and digital signal processing aids (DSP-HA).

Main Methods:

  • A questionnaire audit of user experiences was conducted 3-4 months post-HA fitting.
  • Data were collected from 12,866 respondents (68.8% response rate) out of 18,702 individuals fitted with HAs between 1997-1999.
  • The study population had a median age of 77 years, with a representative distribution of age, gender, and HA type.

Main Results:

  • 71.5% of users reported satisfaction with their HAs; 89% used them daily/weekly, and 75% could manipulate them without issues.
  • Users reported significantly higher satisfaction with A-HAs compared to P-HAs and DSP-HAs.
  • While more users could manipulate DSP-HAs, they required more follow-up visits (36.5%) compared to P-HAs (25.5%) and A-HAs (21.6%).
  • A notable percentage (10.7-12.7%) never used their fitted HAs.
  • Elderly users demonstrated a significantly lower ability to manipulate their HAs.

Conclusions:

  • Modern hearing aid users report high satisfaction and usability, though analogue hearing aids (A-HA) are preferred over digital signal processing aids (DSP-HA).
  • Digital signal processing aids (DSP-HA) may create unrealistic user expectations and incur higher costs for healthcare services due to increased expense and staff resource needs.
  • Targeted user education and support are essential, particularly for elderly individuals and users of advanced DSP-HA technology, to optimize hearing aid adoption and benefit.
