Plain English Summary

Background and study aims
One of the main challenges faced by people with hearing loss is understanding speech in noisy environments. Hearing aids can be of some benefit in these situations, but in isolation they are unable to fully overcome the problem. If the hearing-impaired listener is unable to understand conversations in everyday listening environments they risk becoming socially withdrawn and isolated. Auditory training involves structured practice listening to a variety of stimuli and is gaining support as an alternative to hearing aids or a supplementary intervention. Many of the auditory training programs currently available are administered using a computer which may not be appropriate for many older hearing-impaired adults who do not have access to computers. There is therefore a need to develop a non-computerised auditory training intervention which can be delivered easily in the person's home. The aim of this study is to find out whether a new auditory training program, which involves having conversations in the presence of a competing speaker, improves speech perception in everyday challenging listening environments.

Who can participate?
Experienced adult hearing aid users

What does the study involve?
Participants complete a speech and cognition assessment and then undertake a four-week training program at home. They are randomly allocated to one of two training programs using a CD containing either silence (Group 1) or a person speaking (Group 2). Participants are required to play this CD while having a conversation with their communication partner. Each session lasts for 30 minutes and participants are asked to complete this five times per week for four weeks. Their speech in noise performance and cognitive abilities are then evaluated again.

What are the possible benefits and risks of participating?
By taking part in the study participants may see an improvement in their understanding of speech in challenging listening environments. There are no significant risks to taking part as noise levels should not exceed maximum daily noise exposure limits.

Study hypothesisThe primary aim of this study is to explore whether novel auditory training intervention can improve speech intelligibility in noise for experienced hearing aid users. The primary research question is: Does repeated practice improve speech perception in everyday challenging listening environments for experienced adult hearing aid users?

ConditionHearing loss
InterventionParticipants are randomised to either experimental or control groups based on a dynamic adaptive allocation algorithm using stratification variables of age (less than 75 years: 75 years or older) and sex (Male:Female).

Allocation to one of two training programs: a CD containing either silence (Group 1) or a person speaking (Group 2). Participants are required to play this CD while having a conversation with their communication partner. Each session lasts for 30 minutes and participants are asked to complete this five times per week for four weeks.

Participants complete a baseline speech and cognition assessment and then after their four week training program their speech in noise performance and cognitive abilities are evaluated again.
Intervention typeOther
Primary outcome measureSpeech in noise performance, measured using the signal to noise ratio loss on QuickSIN at baseline and after training has been completed
Secondary outcome measures1. Subjective handicap assessed by Total, Social and Emotional scores from the Hearing Handicap Inventory for the Elderly Questionnaire and Glasgow disability measured at baseline and after training has been completed
2. Signal to noise threshold on the Modified Co-ordinate Response Measure measured at baseline and after training has been completed
3. Scores for words and numbers on the Dual Task of Listening and Memory measures, measured at baseline and after training has been completed
