Are Hearing Aids Designed For All Parts Of The World? An Ecological Momentary Assessment Study, Preeti Pandey
Are Hearing Aids Designed For All Parts Of The World? An Ecological Momentary Assessment Study, Preeti Pandey
Dissertations, 2020-current
The affordability of hearing aids (HA) is a significant barrier to ownership in low-and middle-income countries (WHO, 2021). Crowded living conditions in developing countries intensify the complexity of listening environments compared to developed nations. No existing literature compares the listening environment and HA outcomes using real-world measures across these regions. This study aims to 1) compare HA outcomes and listening environments between India and the USA, and 2) evaluate the benefit of premium HAs over basic HAs in both locations. In an observational, multi-location, single-blinded study, nineteen hearing aid users (mean age 69.6 years) participated. Ecological momentary assessments (EMA) were …
The Impact Of Hair Covering Hearing Aid Microphones On Directional Performance, Sara F. Wagner
The Impact Of Hair Covering Hearing Aid Microphones On Directional Performance, Sara F. Wagner
Dissertations, 2020-current
This study examined the effect of hair covering on hearing aid directional microphone performance. Nine adult, experienced hearing aid users (3 males, 6 females; mean age = 64.6 years) with mild to severe, sloping symmetrical sensorineural hearing loss were included in this study. Binaural Oticon Opn 1 receiver-in-the-ear hearing aids with closed domes were used to provide the recommended amplification for each participant. Speech Reception Threshold (dB SNR required for 50% speech understanding) was measured in all combinations of directional microphone (on/off) and hair covering (with/without) resulting in a total of four conditions. Results showed that directional microphones significantly improved …
Speech Understanding And Listening Effort In Noise With A New Speech Processing Algorithm, Abigail E. Compton
Speech Understanding And Listening Effort In Noise With A New Speech Processing Algorithm, Abigail E. Compton
Dissertations, 2020-current
This study examined the effect of a new speech processing strategy (SpeechZone2) in a commercially available hearing aid on speech understanding in noise and self-reported listening effort. Seven adult, experienced hearing aid users (2 males, 5 females; mean age = 64.6 years) with mild to severe, sloping sensorineural hearing loss participated in this study. Binaural Unitron Flex receiver in the ear style hearing aids with closed domes were used to provide the manufacturer prescribed amplification for each participant. The hearing aids were programmed with two separate memories: 1) omnidirectional microphone without SpeecZone2 processing, and 2) adaptive directionality with SpeechZone2 processing. …
