In Focus September 2025
Workshop in Communication in Hearing Science hosted by ORCA Labs
What's in focus Communication in Hearing Science
A developing field: The impact of hearing difficulties on communication
It is well known that communication becomes difficult when you have a hearing loss, especially in the presence of background noise. This makes it surprising that research into the effect of hearing loss and noise on the conversational speech and behavior is a relatively new field of research.
Less than 10 years ago the first studies mainly focused on the effects of noise and hearing loss on the turn-taking timing and dynamics of the speech produced during 2-person conversation. However, the research field has diversified to look at conversations in larger groups and on how movement and gaze behavior is also affected by communication difficulties.
Our research ORCA Labs
Advancing hearing research through real-world group conversations
WSA is a strong player within the research field of conversations in larger groups and on how movement and gaze behavior is also affected by communication difficulties. At ORCA Labs we were the first to use group conversations to compare hearing-aid settings in conversations between two people (Petersen et al., 2022; Petersen & Parker, 2024), showing how being unaided affects both the speaker with hearing loss and their normal-hearing conversation partner.
We further extended this work by looking into triadic conversations, finding that the experience of the person with hearing loss affects the conversation by influencing e.g. the speech levels of the two normal-hearing conversation partners (Petersen, 2024).
Workshop Communication in Hearing Science
ORCA Labs' workshop in Communication in Hearing Science
At the 1-day workshop hosted by ORCA Labs at the WS Audiology Headquarter in Lynge, 32 scientists from 16 different universities and companies spread across the world met to exchange, discuss and challenge scientific findings.
To provide a fresh input, ORCA Labs had invited two researchers from ‘outside’ the field of hearing science to present: Patricia Paggio, Associate Professor at the University of Copenhagen presented how hand-gestures are important to convey meaning and can act to make certain words more audible, even when only listening to the speech without seeing the speaker. Kristian Mortensen, Associate Professor at the University of Southern Denmark, introduced ethnomethodological conversation analysis of the, often subtle and almost unnoticeable, behavioral signs we use during everyday interactions with other people. He especially focused on mishearing/misunderstanding, which is an especially prominent complaint raised by people with hearing loss.
The participants also brought examples of their own work, presented in 20 posters and 2 talks. Although the overall focus was Communication in Hearing Science, the topics presented were diverse and ranged from developing material to better counsel people with listening difficulties on communication strategies over predicting turn-taking events, conversation partners or conversation success from behavior to how head movements are affected by the number and position of conversation partners.
ORCA Labs would like to thank all the researchers who contributed to making it a workshop full of lively discussions and knowledge exchange.
