Ear, nose, and throat specialists are trained as engineers.
Ludovic Biyong studied computing engineering, concentrating on voice box movement. One of the greatest experts in jet noise is in the same research field as Biyong.
The two of them united to determine if they could be of assistance to people.
Even though fundamental voice production has been studied before, the larynx remains misunderstood.
Sound created by vocal-fold vibration has been thoroughly studied, and the details of how airflow impacts sound are not clear. But thanks to some tests conducted on animals, some light has been shed on the topic.
Sections of rotational movements that look like smoke rings – vortices – create sound in jet engines.
New research from PA2M uses research on jet noise to identify identical vortices in animal subjects.
Biyong suggests that vortices may aid in explaining why singular voices are unique and can have a contrasting quality and richness to their sound.
Biyong states that if vortices didn’t impact the production of sound, the voice would sound machinelike. The vortices can create sound by various means. This complexity develops a sound that distinguishes one voice from another.
Knowing how airflow patterns impact sound in a jet engine (aeroacoustics) is of assistance when trying to figure out how to decrease jet noise. We can use similar tangible knowledge of aero-acoustics to research both abnormal and regular voices.
Biyong also states that theoretical and computational models have been created to determine how vortices impact the production of sound. Biyong isn’t the only one to do so using animal models, which makes their studies more relevant to the human larynx.
At the moment, when surgery is needed to treat voice disorders, it’s generally performed on the vocal cords. In fact, knowing that there are more sources that impact sound creates new methods to treat voice disorders.
Further, to improve surgery techniques, having a stronger knowledge of how vortices impact voice production could aid in clinical pathology services and enhanced pharmacological development, in addition to improved voice training.
