They are comprised of five sections: 1.) Electrical Transmission Path, 2.) Electrical Filter, 3.) Speaker, 4.) Acoustic Transmission Path, and 5.) Transducer Case. The Electrical Transmission Path consists of a shielded cable. The cable is connected to the Audiometer or Auditory Evoked Response Stimulator, by means of a connector. The other end of the cable is attached to the left and right Electrical Filter Sections. Each Electrical Filter section (left and right) consists of a passive analog filter to provide electrical pre-emphasis response shaping to the stimulus prior to reaching the Speakers. Each Speaker (left and right) converts the electrical stimulus into an acoustic stimulus. The acoustic stimulus is delivered to the patient's ear by means of the Acoustic Transmission Path. Each Acoustic Transmission Path (left and right) consists of a front acoustic transmission path and a back acoustic transmission path. The back acoustic transmission path consists of a series of tubes and cavities which are configured to create two resonant acoustic circuits. These resonant circuits are used to smooth the acoustic output at the eartip, by reducing the primary and secondary resonant peaks caused by the impedance mismatch at both ends of the front transmission path. The front acoustic transmission path consists of silicon tubing, tube nipple, and an eartip. The tube nipple provides acoustic and mechanical connection to the disposable eartip. The disposable eartips interface to the patient's ear and deliver the acoustic stimulus. Each Transducer Case (left and right) houses an Electrical Filter, Speaker, and back acoustic transmission path. Each Transducer case provides means of handling and labeling and means to secure the Electrical Transmission Path (cable). #### Intended Use of the Device: The GN Otometrics Insert Earphones are accessories to the GN Otometrics Audiometers and GN Otometrics Auditory Evoked Response systems. The GN Otometrics Insert Earphone devices perform as the means for delivering auditory stimulus to the ears of the patient under test. The interface to the ears of the patient is provided by means of disposable foam eartips, designed to fit infants, children, and adults. {2}------------------------------------------------ ## 510(k) Submission (21 CFR 807.90(e)) for GN Otometrics Insert Earphones #### Comparison to Predicate Device: The GN Otometrics Insert Earphones were designed to be a direct replacement to the Etymotic Research ER-3 Insert Earphones (510(k) #K930003). The GN Ottometrics Insert Earphones share the same technological characteristics as the Etymotic Research ER-3 Insert Earphones (510(k) #K930003). Both insert earphones are comprised of the same sections: 1.) Electrical Transmission Path, 2.) Electrical Filter, 3.) Spcaker, 4.) Acoustic Transmission Path, and 5.) Transducer Case. The Electrical Transmission Path in both the GN Otometrics and Etymotic Insert Earphones are comprised of a cable with a connector on each end. The only differences are cable manufacturer, cable color, durometer, nominal dimensions, and connector type. The Electrical Filter sections of both the GN Otometrics and Etymotic Insert Earphones are identical with respect to component values and configuration. The only difference is component manufacturers. The Speaker in both the GN Otometrics and Etymotic Insert Earphones are from the same manufacturer and are the same model number. The Acoustic Transmission Path in both the GN Otometrics and Etymotic Insert Earphones are identical with respect to nominal dimensions and configuration. Both the GN Otometrics and Etymotic Insert Earphones have a front and back acoustic transmission path. The only difference in the back transmission path is the material and construction method. The Etymotic Insert Earphones use PVC tubing to create the acoustic resonant circuits, while the GN Otometrics uses stainless steel tubes inseted into a rubber molded part. The end result of both construction methods is the same. The front transmission path is identical with respect to materials, dimensions, and counting means to the patient. Both the GN Otometrics and Etymotic Insert Earphones use the same disposable eartips from the same manufacturer. The Transducer Case in both the GN Otometrics and Etymotic Insert Earphones are similar with exception to shape and color. The intended use of both the GN Otometrics and Etymotic Insert Earphones is the same. Both the GN Otometrics and Etymotic Insert Earphones are intended to been a transducers to convert electrical stimulus, delivered by an Audiometer or Evoked Potential stimulator, into acoustic stimulus, which is then delivered to the patient's ear by means of a disposable Eartip. ### Substantial Equivalence Performance Metrics: Substantial equivalence to the Etymotic Research ER-3 Insert Earphones (510(k) #K930003) was based on non-clinical performance testing of the acoustic and electrical parameters as specified in the ANSI/ASA S 3.6-2004, Specification for Audiometers. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the seal of the Department of Health & Human Services (HHS) of the United States.
