It is intended for use by a qualified/trained audiologist on both adult and pediatric subjects for measurement and diagnosis of various types of hearing losses.

Device Story

Amplaid AM50 is a programmable admittance meter for clinical middle ear function assessment. Device performs tympanometry (plain/compensated), acoustic reflex testing (ipsilateral/contralateral), reflex threshold determination, and reflex decay measurements. System consists of hardware unit connected via bi-directional RS232 interface to external personal computer. PC handles all keyboard, display, and control functions. Used by audiologists in clinical settings for diagnosis of hearing loss and middle ear pathologies. Output provided via PC display and printer; assists clinicians in identifying conditions like otosclerosis or ossicular chain discontinuity. Benefits include automated testing capabilities and reduced physical footprint compared to predecessors.

Clinical Evidence

Bench testing and user testing were performed to validate safety and effectiveness. No clinical trial data was required or presented.

Technological Characteristics

Programmable admittance meter; bi-directional RS232 computer interface; 115/230 Vac, 50-60 Hz power. Complies with ANSI 1969, ISO 1975, IEC 61027, UL-544, and IEC 601 standards. Dimensions: 11.4" W x 12" D x 4" H; weight: 4.4 lbs.

Indications for Use

Indicated for adult and pediatric patients requiring measurement of acoustic impedance and diagnosis of hearing loss, including evaluation of otitis media, glue ear, eardrum scarring, myringotomy status, ossicular chain discontinuity, ear canal volume, otosclerosis, and stapes fixation.

Regulatory Classification

Identification

An auditory impedance tester is a device that is intended to change the air pressure in the external auditory canal and measure and graph the mobility characteristics of the tympanic membrane to evaluate the functional condition of the middle ear. The device is used to determine abnormalities in the mobility of the tympanic membrane due to stiffness, flaccidity, or the presence of fluid in the middle ear cavity. The device is also used to measure the acoustic reflex threshold from contractions of the stapedial muscle, to monitor healing of tympanic membrane grafts or stapedectomies, or to monitor followup treatment for inflammation of the middle ear.

Special Controls

*Classification.* Class II (special controls). The device, when it is a tympanometer or auditory impedance tester that complies with FDA-recognized consensus standard ANSI S3.39, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 874.9.

## 510(k) Summary of Safety and Effectiveness

- 1. Identification of the Device: Proprietary-Trade Name: Amplaid AM50 Classification Name: Auditory Impedance Tester 77ETY Common/Usual Name: Clinical Admittance Meter
- 2. Equivalent legally marketed devices This product is similar in design and function to the Amplaid 709 Admittance Meter (K802097) and the 770 Admittance Meter (K903066)
- 3. Indications for Use (intended use) The Amplaid AM50 is a Programmable Admittance Meter which can:
- Evaluate middle ear functions such as otitis media, glue ear, eardrum scar tissues, . perform myringotomy status, ossicular chain discontinuity ear canal volume, otosclerosis, stapes fixation.
- Perform Acoustic reflex test. ●
- Determine acoustic reflex threshold .
- . Perform reflex decay test.

It is intended for use by a qualified/trained audiologist on both adult and pediatric subjects for measurement and diagnosis of various types of hearing losses.

- 4. Description of the Device: The Amplaid AM50 ADMITTANCE METER performs plan and compensated tympanometry; Programmed and manual stimuli for ipsilateral and contralateral acoustic reflex; Automatic reflex threshold; and Decay measurements.
- 5. Safety and Effectiveness, comparison to predicate device. The results of bench and user testing indicates that the new device is as safe and effective as the predicate device. The same circuit technology is used in both devices. The only change is packaging and control software, whereby all keyboard, display, and control functions have been moved to the attached (via RS232) personal computer.
