DEVICE: Oscilla (05713557000120)

An electroacoustic device designed to measure the hearing threshold of a patient by presenting words of increasing or decreasing intensity through headphones, which the patient is required to recognize and repeat, to establish the hearing capacity of the patient and to determine if a hearing deficit exists.

An electroacoustic device designed to measure the hearing threshold of a patient by presenting tones of increasing or decreasing intensity through headphones to establish the level at which the patient first becomes aware of the sounds. Changes in tone intensity, frequency, and the recording of patient responses are all performed manually.

An electroacoustic device designed to be used in a clinical setting to measure the hearing threshold of a patient by presenting tones of increasing or decreasing intensity through headphones to establish the level at which the patient first becomes aware of the sounds. A computer or microprocessor in the device automatically produces tones that sweep the audiometric scale and controls tone intensity and frequency. The device also records the patient's responses and may display calculated hearing thresholds. This device may have the capacity to present a fixed frequency or a steadily changing frequency. It may also provide both continuous and pulsed tone outputs.

An electroacoustic device intended for use in a clinical setting to generate tones in the audible range to measure the hearing threshold of a patient by establishing the level at which the patient first becomes aware of the sounds. The device controls tone intensity and frequency either by a computer or manually, and displays/records the patient's responses, typically in the form of an audiogram. It may include a bone vibrator for direct inner-ear stimulation.
