Study finds Galaxy Buds Pro can help manage hearing loss

A new study published in ‘Clinical and Experimental Otorhinolaryngology’, a leading scientific journal dedicated to ear, nose, and throat (ENT) research, has indicated that Galaxy Buds Pro’s Ambient Sound feature can help those with mild-to-moderate hearing loss to hear surrounding sounds better.

The research was carried out in partnership with Samsung Medical Center, Asia’s leading hospital, with outstanding health care services and research achievements. Samsung has collaborated with the Center for over 10 years, focusing on the impact that mobile devices can have on hearing, while researching new ways to optimise audio experiences for users.

The outcomes of the study, therefore, mark an important next step in Samsung’s ongoing commitment to joining forces on pioneering innovations that can benefit people in their everyday lives.

The study assessed the efficacy of a hearing aid, a personal sound-amplification product, and Galaxy Buds Pro. According to the authors, no other study has yet included true wireless earbuds when evaluating the clinical performance of hearing devices. The study is the first to demonstrate the potential benefit of true wireless earbuds for individuals with mild-to-moderate hearing impairments, and has the potential to improve the lives of 1.5 billion people globally who are currently living with some degree of hearing loss¹.

“With rapidly aging populations, it’s expected that, by 2050, one in 10 people will have hearing loss,” said Il Joon Moon, Associate Professor at the Samsung Medical Center’s Department of Otorhinolaryngology.

“But while hearing aids are useful for managing hearing impairments, uptake remains relatively low, mainly due to the high price.

“The initial study findings are very promising and encourage people to discover alternative devices, such as Galaxy Buds Pro, that can support them in their day to day lives.”

Galaxy Buds Pro, the hearing aid and the personal sound amplification product underwent three key tests: electro-acoustic assessment, sound amplification evaluation and a clinical performance evaluation.

Electro-acoustic assessment

Firstly, the electro-acoustic characteristics of each device were assessed to see if they met the key performance criteria for hearing aids: output sound pressure level, frequency range, equivalent input noise, and total harmonic distortion. The results revealed that Galaxy Buds Pro met each of these four criteria, indicating that they show comparable performance to hearing aids.

Sound amplification evaluation

Next, a sound-amplification evaluation was performed to examine if the devices adequately boosted sound. Each device was tested at seven different frequencies, and all showed an appropriate level of amplification.

Clinical performance evaluation

Finally, a clinical performance evaluation investigated changes in individuals’ hearing levels, both with and without the devices, and their ability to recognise words and sentences. Participants had mild-to-moderate hearing loss, with a median age of 63 years.

Statistical significance was observed at 1,000Hz, 2,000Hz and 6,000Hz, meaning Galaxy Buds Pro sufficiently amplified sound at the three frequencies of speech pitches. Furthermore, in total, over 57 per cent of the participants reported that Galaxy Buds Pro were able to help them communicate in a quiet environment.

It was also discovered that, while wearing Galaxy Buds Pro, individuals were able to understand spoken words better – the results found statistically significant improvement in performance for the three devices compared to that in the unaided condition. This suggests that, along with hearing aids and personal sound amplification products, Galaxy Buds Pro could potentially provide communicative benefit for individuals with hearing loss, and especially for those with mild-and-moderate loss.

“As we develop new products and services, we are mindful of how our technology can help people to defy barriers and do more,” says Han-gil Moon, Master and Head of Advanced Audio Lab, Mobile Communications Business at Samsung Electronics.

“These findings reflect our ongoing commitment to creating innovations that enable everyone to better enjoy everyday experiences, and we plan to extend the test to more participants in the coming months.”

Galaxy Buds Pro feature Ambient Sound, which can amplify nearby sounds by up to 20 decibels and, with four levels to choose from, users are able to adjust and customise how they experience sound according to their needs.
