1. Acoustic apparatus using bone-conduction speaker

2. Bone conduction hearing device having acoustic feedback reduction system

3. Audiometry, pure tone bone conduction Audiometry, and/or speech discrimination testing

4. The present invention relates to a voice coil structure for a bone-conduction speaker.

5. The acoustic device (1) has a bone conduction speaker (24) for imparting acoustic vibration to an earplug (21).

6. The purpose of tone Audiometry is to establish the hearing sensitivity at various frequencies for air conduction and bone conduction

7. Bone anchored hearing aids (BAHA) achieve optimal acoustic coupling by means of direct bone conduction via an osseointegrated percutaneous titanium implant.

8. Using air (AC) and bone conduction (BC) the vestibular receptors and afferents of the otolith organs can be activated to varying degrees.

9. A bone-Anchored hearing aid (BAHA) is a surgically implantable system for treatment of hearing loss that works through direct bone conduction

10. To ensure the best possible acoustic transduction, the Bone Conduction-Floating Mass Transducer (BC-FMT) should be positioned near to the cochlea.

11. The ATMOS Audiometer is a high-quality, 2-channel sound and speech Audiometer for: Air/bone conduction Treble/high frequency Suprathreshold tests (SISI

12. EKEN Bone Conduction Headphones - Bluetooth 5.0v with Microphone, Titanium Lightweight Wireless Open-Ear Sweat Resistant, Answer Phone Call Headset for Running Hiking Driving Bicycling - Red

13. The small microphone and FM transmitting unit is worn on the Anacoustic ear and transmits the signal to the intraoral device, providing bone conduction to the good ear.

14. Audiometer An instrument for measuring the lowest levels at which pure tones can be heard at each of a range of frequencies, either by air or by bone conduction

15. Learning Objectives Perform a comprehensive audiologic assessment including air conduction, bone conduction, speech Audiometry and immittance measures Identify the type, degree and configuration of a hearing loss recommend further tests and/or the candidacy for amplification

16. So Diver A and Diver B both have a wearable computer and the dolphin hears the whistle as a whistle, the diver hears the whistle as a whistle in the water, but also as a word through bone conduction.

17. Automated Audiometry provides an accurate measure of hearing threshold, but validation data are still limited for (1) automated bone conduction Audiometry; (2) automated Audiometry in children and difficult-to-test populations and; (3) different types and degrees of hearing loss.

18. The bone conduction headphones of the present invention closes the earholes by means of the auxiliary vibration ear rings connected to the main vibration housings, thereby effectively reducing noise from an external source, and thus further improving the listening ability of the user.

19. The present invention relates to Bluetooth bone conduction headphones capable of performing wireless data communication and having auxiliary vibration ear rings for reducing the loss of vibrations transmitted to the human skull as well as for reducing noise from an external source.

20. • measurement of the infant's occluded external ear acoustics using the real-ear to coupler difference (RECD) procedure7 Frequency-specific air conduction (AC) and, when indicated, bone-conduction (BC) threshold estimates must be obtained before proceeding with the prescription and fitting of amplification for young infants.
