Air conduction (250 to 6,000 Hz), bone conduction (500 to 4,000 Hz), and speech recognition threshold (SRT) and speech discrimination
scores were determined in both ears of participants via a TDH-39 earphone.
The ability to understand speech was evaluated using speech discrimination
scores were found between 68 and 72% in high-level hearing loss and 92 and 96 % in moderate level hearing loss.
Central auditory processing declines in the old, impairing speech discrimination
especially in the presence of background noise(5)(6)(7)(8)(9)(10)(11)(12).
The fitting of binaural amplification is preferred because of enhanced speech discrimination
capability in noise and improved localization ability, which is difficult to achieve with a monaural fitting.
Mechanical equipment and building noises, movement of chairs, background music, and buzzing lights can all impede speech discrimination
Auditory outcomes were quantified by the speech reception threshold (SRT), the speech discrimination
test (SDT), scores on the Korean version of the Glendonald Auditory Screening Procedure (GASP-K), and categories of auditory performance (CAP) scores.
Speech comprehension continues to be difficult for the patient, with speech discrimination
scores being less than 50 percent in both ears.
Furthermore, the additional use of a standard Cl was advantageous for speech discrimination
in our patient.
Following treatment, he demonstrated an elevation of pure-tone audiometric thresholds and a sudden decrease in speech discrimination
score (SDS) to 0%.
