Intended Use

Otogram can perform the functions of: 1. Pure tone and speech audiometer. 2. Impedance audiometer (tympanometry, acoustic reflex), and 3. Distortion product otoacoustic emissions analyzer. The unit is intended for use by a qualified/trained audiologist on both adult and pediatric subjects for measurement of acoustic impedance.

Device Story

Otogram is a computer-controlled audiometric instrument combining pure tone/speech audiometry, impedance audiometry (tympanometry, acoustic reflex), and distortion product otoacoustic emissions (DPOAE) analysis. Device inputs include acoustic signals for testing; system is controlled via ASCII commands from a PC running proprietary software. Device performs measurements and outputs results to a display or printer. Used in clinical settings by audiologists to diagnose hearing and otologic disorders. System integrates with NOAH v.3 hearing aid fitting software. Benefits include comprehensive diagnostic capability in a single platform, aiding clinical decision-making regarding patient hearing health and cochlear function.

Clinical Evidence

Bench and user testing performed. No clinical trials on human subjects reported. Testing confirmed performance metrics and safety parameters (e.g., pressure range, frequency accuracy) are consistent with predicate devices and relevant standards (IEC 1027, ANSI S3.39).

Technological Characteristics

Combined audiometer, impedance meter, and DPOAE analyzer. Features peristaltic pump (stepper motor controlled), resistive touchscreen, and PC-based control via RS-232. Connectivity: RS-232, USB, parallel port. Standards: IEC 1027, ANSI S3.39, EN 60601-1 (Class I, Type B). Thermal printer output. Multi-language support.

Indications for Use

Indicated for adult and pediatric patients requiring audiometric testing, acoustic impedance measurement (tympanometry, acoustic reflex), and distortion product otoacoustic emissions analysis. Intended for use by qualified/trained audiologists.

Regulatory Classification

Dear Mr. Kamm:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean I hat FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
