“…According to a recent study, the brain would quickly adapt to the amplification within two weeks. Still, it would take up to six weeks to fully interpret the amplified signals meaningfully [ 45 ]. Here, the PSAPs were not gradually adapted to hearing and were only worn for one session of three hours, which could explain the small yet significant benefits and interindividual variability.…”

Objective The aging population is prone to hearing loss, which has several adverse effects on quality of life, including difficulty following conversations in noisy environments. Personal Sound Amplification Products (PSAPs) are a less expensive, over-the-counter alternative to traditional, more expensive hearing aids. Although some studies have shown that PSAPs can mitigate hearing loss, the literature generally only addresses group differences without considering interindividual variability. This study aimed to 1) determine how PSAPs affect listening effort and speech perception in noise and 2) measure interindividual variability and identify contributing demographic and health factors. Design We used a cross-over design in which all participants were assigned to each condition. Participants Twenty-eight adults aged 60 to 87 years with normal hearing and mild hearing loss fulfilled the study requirements. Intervention In one session, speech-in-noise perception tasks were performed without PSAPs, and in the other, the tasks were performed with bilateral PSAPs. The two sessions were separated by one week, and the order of the sessions was balanced across participants. Main outcome measures In both sessions, participants performed the Quick speech-in-noise test and a word discrimination task in noise, in which their self-reported listening effort was measured. Results PSAPs use improved speech perception in noise in both tasks and reduced listening effort. There was considerable variability between individuals, with approximately 60–70% of participants showing benefit. Age, hearing and cognitive status were significant predictors of the benefits. Conclusion Not all individuals may benefit from the effect of PSAPs to the same extent at their first use, and this depends on specific health and demographic factors, particularly age, hearing, and cognitive status. These results underscore the importance of demographic and health factors in assessing the benefits of hearing amplification in older adults. Trial registration ClinicalTrials.gov, NCT05076045.

“…Hearing aid users are 14.5% less exhausted at the end of the day compared to non-hearing aid users with similar hearing loss and are less likely to experience depression or memory loss [11]. It has been proven that the use of hearing aids stimulates the plasticity of the brain, and after 4 weeks, the records in the cortical auditory evoked potentials' change [28,29]. Moreover, for patients with moderate hearing loss, the use of hearing aids has a suppressive effect on cognitive impairment [18].…”

Hearing loss is one of the most common causes of disability worldwide. The aim of the study was to compare the demographic structure and the results of hearing tests in people qualified for hearing aids over the last 25 years. The material covered 1246 patients qualified for hearing aids in the years 1996–2001 and 2016–2021. Patients were divided into two groups according to the time of qualifying for hearing aids. Group 1 (G1) consisted of 759 people qualified in the years 1996–2001, and Group 2 (G2) comprised 487 people qualified in the years 2016–2021. Statistical analysis was performed on the results of pure tone threshold audiometry and the demographic structure in both groups. Patients in G1 had statistically significantly elevated hearing thresholds (HT) in the air conduction range at frequencies from 2000 to 8000 Hz in relation to G2 patients. The opposite situation was observed for the bone conduction threshold. G2 patients had significantly elevated bone conduction HT at frequencies from 250 to 1000 Hz compared to G1 patients. The age structure in both groups was similar; however, the gender distribution was statistically significantly different. In G1 women accounted for 40%, and in G2, they became the dominant gender (53%). Over the last twenty years, there has been a change in the structure of patients qualified for hearing aids. Although the age has remained similar, today, patients decide to use hearing aids at an earlier stage of hearing loss than 25 years ago. Modern women began to use hearing aids much more often.

“…The most difficult environments and the lowest scores were noted when speech was presented in a background noise condition compared to quiet or music conditions. Therefore, although HAs have been shown to improve cognitive and cortical function ( Karawani et al, 2018b ; Glick and Sharma, 2020 ; Karawani et al, 2022 ), and perceptual abilities ( Munro and Lutman, 2003 ; Lavie et al, 2015 ; Megha and Maruthy, 2019 ; Wright and Gagné, 2020 ), the benefits of speech in noise processing are limited ( Sweetow and Sabes, 2006 ; Humes et al, 2009 , 2013 ; Kaplan-Neeman et al, 2012 ; Karawani et al, 2018a ; Bieber and Gordon-Salant, 2021 ).…”

Older adults with age-related hearing loss often use hearing aids (HAs) to compensate. However, certain challenges in speech perception, especially in noise still exist, despite today’s HA technology. The current study presents an evaluation of a home-based auditory exercises program that can be used during the adaptation process for HA use. The home-based program was developed at a time when telemedicine became prominent in part due to the COVID-19 pandemic. The study included 53 older adults with age-related symmetrical sensorineural hearing loss. They were divided into three groups depending on their experience using HAs. Group 1: Experienced users (participants who used bilateral HAs for at least 2 years). Group 2: New users (participants who were fitted with bilateral HAs for the first time). Group 3: Non-users. These three groups underwent auditory exercises for 3 weeks. The auditory tasks included auditory detection, auditory discrimination, and auditory identification, as well as comprehension with basic (syllables) and more complex (sentences) stimuli, presented in quiet and in noisy listening conditions. All participants completed self-assessment questionnaires before and after the auditory exercises program and underwent a cognitive test at the end. Self-assessed improvements in hearing ability were observed across the HA users groups, with significant changes described by new users. Overall, speech perception in noise was poorer than in quiet. Speech perception accuracy was poorer in the non-users group compared to the users in all tasks. In sessions where stimuli were presented in quiet, similar performance was observed among new and experienced uses. New users performed significantly better than non-users in all speech in noise tasks; however, compared to the experienced users, performance differences depended on task difficulty. The findings indicate that HA users, even new users, had better perceptual performance than their peers who did not receive hearing aids.
