Exclusion Criteria
Those who violate any of the following will not be included in this study. 1) Those with hearing loss with significant fluctuations in hearing 2) Those who have a disease other than hearing loss that makes orientation test impossible. 3) Those who are judged to be inappropriate as research subjects by the person responsible for the research.
Study & Design

- Observational
- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Directional localization ability indices and various conditions for sound localization test *Calculate the direction localization ability index for each presented sound, and compare each group at a significance level (both sides) by a two-group test that takes into account age, gender, standard pure tone audiometry, morbidity period, wearing period, hearing aid wearing threshold test, pitch match/loudness balance test, and HHIA (questionnaire survey) among the background factors.
- Secondary Outcome Measures
Name Time Method Association of various hearing tests results toward both directional localization ability indices and various conditions for sound localization test *Unilateral highly sensorineural hearing loss, unilateral highly mixed hearing loss, good hearing:=<30 dB HL (0.5, 1, 2, 4 kHz, respectively) & >80 dB HL (0.5, 1, 2, 4 kHz, respectively) are the secondary endpoint target groups. Directional localization ability indices are calculated for each indicated sound, and among the background factors, age, gender, standard pure tone audiometry, morbidity period, wearing period, threshold test for wearing hearing aids, pitch match/loudness balance test, and HHIA are taken into account to compare the presentation sound pressure and noise type by group at a significance level (both sides) of 5%.
