Preferred listening levels of mobile phone programs when considering subway interior noise.

Today, people listen to music loud using personal listening devices. Although a majority of studies have reported that the high volume played on these listening devices produces a latent risk of hearing problems, there is a lack of studies on "double noise exposures" such as environmental noise plus recreational noise. The present study measures the preferred listening levels of a mobile phone program with subway interior noise for 74 normal-hearing participants in five age groups (ranging from 20s to 60s).

Speech perception enhancement in elderly hearing aid users using an auditory training program for mobile devices.

Aims: The goal of the present study was to develop an auditory training program using a mobile device and to test its efficacy by applying it to older adults suffering from moderate-to-severe sensorineural hearing loss.

Methods: Among the 20 elderly hearing-impaired listeners who participated, 10 were randomly assigned to a training group (TG) and 10 were assigned to a non-training group (NTG) as a control. As a baseline, all participants were measured by vowel, consonant and sentence tests.

Speech perception in older listeners with normal hearing:conditions of time alteration, selective word stress, and length of sentences.

Background And Objectives: Deficits of the aging auditory system negatively affect older listeners in terms of speech communication, resulting in limitations to their social lives. To improve their perceptual skills, the goal of this study was to investigate the effects of time alteration, selective word stress, and varying sentence lengths on the speech perception of older listeners.

Subjects And Methods: Seventeen older people with normal hearing were tested for seven conditions of different time-altered sentences (i.
