For people who have hearing loss, the phrase “music to my ears” could have a completely new meaning.

Exposing children to music can have a worthwhile effect on hearing as is illustrated by a joint study carried out by the University College London and the University of Helsinki.

Evaluating Speech-in-Noise Performance

Speech-in-noise performance was the main measure researchers looked at, putting 43 young children in a clinical study for 14 to 17 months. 22 of the children observed had normal hearing while the remaining 21 had cochlear implants. The researchers already knew that children with implants had a difficult time understanding speech so they introduced control and test sets which delegated participants to singing and non-singing groups.

For kids in the singing group, a significant improvement in awareness and speech-in-noise performance was revealed in comparison with children in the non-singing group.

Music Trains The Ear

This research is just the latest in a long line of research efforts that show the merits of musical training to enhance cognitive ability and speech processing. In noisy environments, speech perception can be improved by musical training, and these findings were backed by a study carried out by the Montreal Neurological Institute

Identifying speech syllables through a variety of background noises was the goal of this study which analyzed 15 musicians and 15 non-musicians.

Unlike the research out of Helsinki and London, Drs. Yi and Robert’s study evaluated young adults whose ages averaged around 22-years-old. These participants had normal hearing but there was a considerable difference in results between the musicians and the non-musicians.

Non-Musicians Were Outperformed By Musicians

When the noise was missing, both groups had comparable results, but when any amount of background noise was incorporated, the musicians substantially outperformed the non-musicians. Musicians have enhanced left interior frontal and right auditory regions of the brain which probably accounts for this ability to perform well on these tests.

But the benefits of musical training revealed by Drs. Yi and Robert’s study don’t just end there. According to the study’s conclusions, musical training strengthened the participant’s auditory-motor network, fine-tuning and uniting the auditory system and speech motor system to improve hearing.

These adult musicians in this study had all been trained when they were younger and had at least a decade of training. This once again backs the recent assessment that musical training can have a powerful impact.

Beethoven’s Fight With Hearing Loss

Hearing loss has been a problem for some of the world’s most famous composers and musicians. Most notably, Ludwig van Beethoven who began to lose his hearing in his 20’s.

The early groundwork of Beethoven’s training, though severe, was probably the gateway for prolonging his musical career. As a matter of fact, Beethoven actually spent the last 10 years of his life nearly completely deaf. In spite of that, many of his most beloved works were composed over his last 15 years.
