“
And made important contributions to the detection of hearing loss.
“
Among his 30 patented inventions, Bell created the audiometer, which he used to test the hearing of hundreds of people, including children.

Bell Telephone Laboratories devised this sound measurement unit and named it “bel”—in honor of the organization’s founder.
