Description
The ER-7C probe microphone is specially designed to perform accurate measurements of the sound pressure in the ear and is often used in studies that require precise measurement of sound levels within the ear canal.
The ER-7C can be used, for example, to calibrate hearing aids, conduct hearing tests, and for research into how sound is perceived by the human ear. The device is designed to fit in the ear canal and ensures minimal disturbance of the sound field, allowing for highly accurate measurements.
