Those who put off getting their teeth checked because they fear the whirring of the dental drill may have a solution.
A handheld personal audio system known as b-Calm disguises the high-pitched frequency of drilling using nature-inspired sounds such as waves, the Des Moines Register reports.
Previous attempts to cancel out drilling with music or other sounds led to the discovery that people's minds tended to focus on the new noise instead of relaxing.
Three years of research led to b-Calm's AudioSedation technology, which claims to erase the disturbance of the drill by blending it with other sounds at a particular frequency, then adding audio tracks from nature.
Using a touchpad, the listener can control the volume and skip ahead to the next track.
Patient Renee Bunger told the publication the device has improved her experience in the dental chair.
"I actually think it's a wonderful product. The sound of the ocean was a definite plus," she said.
