Does bilateral hearing aid fitting improve spatial hearing ability: a systematic review and meta-analysis.

Objectives: The ability to localize sound sources is crucial for everyday listening, as it contributes to spatial awareness and the detection of warning signs. Individuals with hearing impairment have poorer localization abilities, which further deteriorate when they are fitted with a hearing aid. Although numerous studies have addressed this phenomenon, there is a lack of systematic evidence.

Temporal fine structure mediated recognition of speech in the presence of multitalker babble.

This experiment investigated the mechanisms of temporal fine structure (TFS) mediated speech recognition in multi-talker babble. The signal-to-noise ratio 50 (SNR-50) for naive-listeners was measured when the TFS was retained in its original form (ORIG-TFS), the TFS was time reversed (REV-TFS), and the TFS was replaced by noise (NO-TFS). The original envelope was unchanged.

Association of auditory steady state responses with perception of temporal modulations and speech in noise.

Amplitude modulations in the speech convey important acoustic information for speech perception. Auditory steady state response (ASSR) is thought to be physiological correlate of amplitude modulation perception. Limited research is available exploring association between ASSR and modulation detection ability as well as speech perception.
