Objective

2

To understand the satisfaction of elderly hearing impaired patients with hearing aids in their daily lives

and to provide scientific basis for improving the technical level of fitting profession and enhancing satisfaction in the future.

Method

2

Elderly people with hearing impairments who were previously tested and wearing hearing aids at the chain store of Nanning-Xinshengda Hearing Equipment Technology Co. Ltd. in Guangxi were selected as the research subjects. The SADL scale was used to survey the degree of hearing loss

type of hearing aid

noise reduction function

number of channels

multiple microphones

historical wearing time

daily wearing time

and 15 items of the SADL survey scale. The scores of positive effects

service prices

negative effects

self-image and appearance

and total average were calculated. SPSS25.00 statistical software was used for inter group mean comparison t-test or F-test and multiple linear stepwise regression analysis.

Results

2

319 people were surveyed

with a total average score of 5.15

standard-reaching rate of 63.95%

the positive effect score of 5.60

standard-reaching rate of 85.27%

the service and price score of 5.69

and standard-reaching rate of 83.70%. However

the negative effect score was 3.06

and the self-image and appearance score was 4.46

which was lower than the SADL standard score. Univariate analysis showed that in the positive effect dimension

there were statistically significant differences in age

number of channels

and wearing time (

P

<

0.05). In the service and price dimensions

the difference in multiple microphones was statistically significant

while the other univariate analyses showed no statistically significant differences. Multiple linear regression analysis showed that in the positive effect dimension

three independent variables: channel numbers

multiple microphones

and wearing time were introduced into the equation. In the dimensions of service and price

multiple microphones are introduced into the equation

while no variables were introduced in the other dimensions.

Conclusion

2

The average satisfaction score and standard-reaching rate of SADL are relatively high

and multiple microphones and wearing time have a positive correlation

while the number of channels has a negative correlation. Hearing aid fitter need to strengthen communication with wearers

set reasonable expectations

and enhance learning of new technologies to improve wearing satisfaction.
