Intended Use

The Amplaid A724 A728 are Programmable Admittance Meters 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.

Device Story

Amplaid A724 and A728 are clinical admittance meters; used by audiologists in clinical settings to evaluate middle ear function. Device performs plane and compensated tympanometry; ipsilateral and contralateral acoustic reflex testing; reflex threshold determination; reflex decay measurements. Input involves acoustic stimuli; device processes impedance/admittance data; output provided via built-in thermal printer and liquid crystal display. Bi-directional RS232 interface allows data transfer. Results assist clinicians in diagnosing conditions like otitis media, stapes fixation, and ossicular chain discontinuity; facilitates clinical decision-making regarding hearing loss management.

Clinical Evidence

Bench testing only. No clinical data provided. Safety and effectiveness established through comparison of technical specifications and performance against the predicate device, confirming compliance with relevant IEC and ANSI standards.

Technological Characteristics

Clinical admittance meter; performs tympanometry and acoustic reflex testing. Features built-in LCD, keyboard, and thermal printer. Connectivity: Bi-directional RS232. Energy: 115/230 Vac, 50-60 Hz. Standards: IEC 61027 (1993), ANSI S3.39 (1987), ANSI S3.6 (1996), EN 60601-1 Class I Type BF (1990).

Indications for Use

Indicated for adult and pediatric patients requiring evaluation of middle ear function (e.g., otitis media, ossicular chain discontinuity, otosclerosis) and acoustic reflex testing (threshold and decay) for the diagnosis of hearing loss.

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.
