No
The device description explicitly details hardware components including a generator/amplifier unit, a piezoelectric transducer, a headband, and a battery. It generates ultrasound energy through these physical components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
- Device Function: The HiSonic-TRD tinnitus masker is a device that generates sound (ultrasonic, bone conducted broadband noise and/or sweep frequency stimuli) and applies it to the mastoid bone to help manage tinnitus. It does not analyze any biological samples from the patient.
- Intended Use: The intended use is for tinnitus habituation and masking therapy, which are therapeutic interventions, not diagnostic procedures involving the analysis of biological specimens.
Therefore, the HiSonic-TRD falls under the category of a therapeutic medical device, not an In Vitro Diagnostic.

Device Description
The HiSonic-TRD generates ultrasound energy and couples the energy to the mastoid bone in order to activate the auditory nervous system, and produce auditory sensations that mask tinnitus. The device consists of a generator/amplifier unit, a piezoelectric transducer, and a headband to hold the transducer firmly against the mastoid bone. A 7.2V Lithium Ion battery powers the device. The tranducer is a piezoelectric ceramic that transmits ultrasonic energy in a typical operating frequency bandwidth of 19.5kHz-25.8kHz to the user. The generator/amplifier unit is worn on the body and houses the lithium ion battery. In addition, the body worn unit has an "on/off" switch, a noise/sweep selector switch and a volume control wheel for use by the patient. Both broadband noise and sweep frequency stimuli are incorporated in the device as masking stimuli. The HiSonic-TRD generates and amplifies electronic oscillations, and then converts them into ultrasound energy with a piezoelectric ceramic transducer. The ultrasound energy is emitted as a broadband noise or as a sweep frequency.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The company has conducted several safety and efficacy studies.
The University of Illinois Bioacoustics Research Laboratory measured the ultrasound energy emitted by the HiSonic-TRD at maximum output power levels against known injury mechanisms. The output intensity data were calculated against a standard thermal model supported by theoretical and experimental studies on blood and intact tissues. The ultrasound energy has been shown to be too low to produce thermal damage and too low to produce any other known damaging bio-effects. The output satisfies the safety limits of IEC 61689.
In a separate study, the University of Illinois Bioacoustics Research Laboratory, performed calibration measurements on the company's HiSonic-TRD device. The results of the calibration measurements demonstrated that the device is calibrated and that due to the low level of acoustic intensity (mw/cm²) output power, generated by the HiSonic-TRD device that it is not possible to reach unsafe acoustic intensity output levels with the device, even at the highest possible setting on the volume wheel.
A safety study was conducted using eleven human subjects at the University at Buffalo Speech-Language and Hearing Clinic. Subjects ranged in age from 22-70 years, six females and five males. Subjects had normal hearing, hearing loss, tinnitus and no tinnitus present. The study was conducted to examine any changes in auditory thresholds, speech intelligibility and any extra-auditory effects that might occur when using the HiSonic-TRD device. The results demonstrated that there were no significant changes in threshold, there was no decrease in speech discrimination and no interference with speech understanding. With the exception of headaches reported in two subjects the study reported no adverse events as a result of patient use of the device. The safety of the HiSonic-TRD is comparable to the safety of the predicates.
An efficacy study was conducted using twenty human subjects at the Oregon Health Sciences University Tinnitus Clinic. The study was conducted to evaluate the ability of HiSonic-TRD devices to produce clinically useful masking of tinnitus and to determine the effect of any aftereffects. The selection criteria required that each subject's tinnitus was present for at least twelve months and that the tinnitus showed little variability in loudness, localization or sound quality. Baseline air-conduction sound thresholds were measured across the audible range of hearing on all subjects prior to tinnitus assessment. The HiSonic-TRD device was evaluated using a threshold approach to audibility. The dynamic range (threshold to uncomfortable level) was measured and then the masking effects were assessed. The data obtained from this study indicate that the ultrasound emitted by the device is audible and produces effective masking in patients with clinically significant tinnitus. All subjects were easily able to hear the HiSonic-TRD masking sound (both sweep frequency tones and narrow band noise). The rate of masking achieved with the HiSonic-TRD device was similar to or slightly exceeded the rate of masking observed with FDA cleared tinnitus maskers. In addition, the study demonstrated a lack of interference with the patient's ability to hear ambient sounds during tinnitus masking. The study showed no adverse events as a result of patient use of the device.

Intended Use
The HiSonic-TRD tinnitus masker is a wearable behind-the-ear style ultrasonic, bone conducted broadband noise and/or sweep frequency stimuli noise generator intended to generate noise of sufficient intensity and bandwidth to be used for tinnitus habituation therapy and is also suitable for tinnitus masking therapy. The HiSonic-TRD is intended to be used by those individuals who experience tinnitus, and do not need or desire amplification. The intended use of the HiSonic-TRD includes it's fitting by a qualified audiologist or other hearing healthcare professional familiar with the diagnosis of tinnitus and subsequent rehabilitation therapies. The target population is the adult population over 18 years of age. This product is not intended for use in children under the age of 18.
Technological Characteristics and Substantial Equivalence
The HiSonic-TRD generates ultrasound energy and couples the energy to the mastoid bone in order to activate the auditory nervous system, and produce auditory sensations that mask tinnitus. The device consists of a generator/amplifier unit, a piezoelectric transducer, and a headband to hold the transducer firmly against the mastoid bone. The bone conducted energy coupling of the HiSonic-TRD device is substantially similar to that used by two of the predicate devices (ADM-Tronic's Aurex-3; HiSonic Hearing Instrument). The HiSonic-TRD device produces auditory sensations that are substantially similar in effectiveness to that of the predicate tinnitus maskers (the Starkey Labs TM and TM-5 and the Aurex-3).

A 7.2V Lithium Ion battery powers the device. The tranducer is a piezoelectric ceramic that transmits ultrasonic energy in a typical operating frequency bandwidth of 19.5kHz-25.8kHz to the user. The generator/amplifier unit is worn on the body and houses the lithium ion battery. In addition, the body worn unit has an "on/off" switch, a noise/sweep selector switch and a volume control wheel for use by the patient. Both broadband noise and sweep frequency stimuli are incorporated in the device as masking stimuli.
The HiSonic-TRD generates and amplifies electronic oscillations, and then converts them into ultrasound energy with a piezoelectric ceramic transducer. The ultrasound energy is emitted as a broadband noise or as a sweep frequency.
The HiSonic-TRD is substantially equivalent to the other currently marketed tinnitus maskers that are referenced above. The HiSonic-TRD and three of the predicate devices are all tinnitus maskers. In addition, the Company's own 510(k) for an ultrasonic hearing instrument (K951678) supports equivalence of the HiSonic-TRD with regard to the piezoelectric ceramic transducer used to generate the ultrasound. Thus, the HiSonic-TRD raises no new issues of safety or effectiveness.
Performance Data
The company has conducted several safety and efficacy studies.
The University of Illinois Bioacoustics Research Laboratory measured the ultrasound energy emitted by the HiSonic-TRD at maximum output power levels against known injury mechanisms.

the device is calibrated and that due to the low level of acoustic intensity (mw/cm²)*, output power, generated by the HiSonic-TRD device that it is not possible to reach unsafe acoustic intensity output levels with the device, even at the highest possible setting on the volume wheel.
*The measured output of acoustic devices intended for use in the audiology market is specified in dbSPL (decibels, sound pressure level) for air-borne devices and bone conducted auditory devices. If the available national or international measurement standards were applied to the HiSonic-TRD device, the output data would be misleading. The company provides exposure data in terms of fundamental physical principles. The output of the device is quantified in terms of the temporal-average acoustic power. The unit of measure is the watt. The acoustic power is then normalized to the area of the transducer element; the area is 1.27cm². The ratio of acoustic power to area is defined as acoustic intensity. Watts/cm2=Acoustic intensity. Due to the low level of output power generated by the HiSonic-TRD the acoustic intensity is reported in milliwatts per cm2 (mw/cm2).
A safety study was conducted using eleven human subjects at the University at Buffalo Speech-Language and Hearing Clinic. Subjects ranged in age from 22-70 years, six females and five males. Subjects had normal hearing, hearing loss, tinnitus and no tinnitus present.
