  • Understanding Digital Frequency Compression
  • This brings us to the question, Who is a candidate for frequency compression? Clients with thresholds 65-70dB or poorer at 2KHz and above are candidates. Once you see greater than 35dB per octave slope, cochlear dead regions must be suspected. The research is pretty conclusive on this. Inability to detect and/or recognize /s/, /sh/. Clients whose speech recognition scores are poorer than one would be expected based on puretone thresholds. Poor tonal perception. Hearing loss as a result of ototoxicity i.e. chemo patients.

    1. 1. Welcome <ul><li>Al Turri, Au.D. </li></ul><ul><li>[email_address] </li></ul>
    2. 2. Two New Technologies <ul><li>Receiver in the Canal </li></ul><ul><li>Frequency Compression </li></ul>
    3. 3. In total: 30 million Americans, 10% of the population. 10%
    4. 4. Don’t accept this isolation. Helen Keller said: “ Blindness separates you from things. Deafness separates you from people.”
    5. 5. Receiver In the Canal <ul><li>Appropriate for people with mild-to-severe hearing loss. (This is more than half of all people who need hearing aids.) </li></ul><ul><li>Addresses high, mid-range and low-frequency hearing loss. </li></ul>a major breakthrough.
    6. 6. <ul><li>The first hearing aid that places a tiny speaker directly in the ear while keeping the canal open. </li></ul><ul><li>The speaker floats in the canal. </li></ul>vs. TOC (totally open canal).
    7. 7. You <ul><li>While all occluding hearing aids give you a hearing loss and force you to “start over”... </li></ul>+ RIC = More <ul><li>With Vivatone, you keep all the hearing you already have. </li></ul><ul><li>Vivatone adds to it. </li></ul><ul><ul><li>Vivatone takes advantage of the natural amplification of your ear. </li></ul></ul><ul><ul><li>Provides amplification only </li></ul></ul><ul><ul><li>in the frequencies you need. </li></ul></ul>
    8. 8. What my patients say...
    9. 9. <ul><li>Hear the soft, subtle sounds of the world: </li></ul><ul><ul><li>Footsteps. </li></ul></ul><ul><ul><li>Birdsong. </li></ul></ul><ul><ul><li>Whispers. </li></ul></ul>
    10. 10. <ul><li>Hear your spouse, hear children. </li></ul><ul><li>Hear what you want to hear, rather than everything else. </li></ul><ul><li>Hear the sounds that enrich your life: </li></ul><ul><ul><li>Rustling of paper. </li></ul></ul><ul><ul><li>Clink of silverware. </li></ul></ul>
    11. 11. RIC lets you hear beginnings and endings of words. <ul><li>Knife and nice. </li></ul><ul><li>Pick and pit. </li></ul><ul><li>Fed and said. </li></ul><ul><li>Fail and sail. </li></ul><ul><li>Chief and cheat. </li></ul><ul><li>And thousands more! </li></ul>D I FF ER EN C E Hear the difference between:
    12. 12. Other advantages of RIC: <ul><li>Remarkably comfortable. </li></ul><ul><li>Virtually invisible. </li></ul><ul><li>Lightweight, (users are unaware of it!) but rugged. </li></ul>Can you see it?
    13. 13. 100% digital. <ul><li>The hearing aid is the computer chip. The software can be changed for virtually unlimited processing. </li></ul><ul><li>Exceptional sound quality. </li></ul><ul><ul><li>Enhanced clarity. </li></ul></ul><ul><ul><li>More detail in speech. </li></ul></ul><ul><ul><li>Greater sharpness and brilliance. </li></ul></ul>
    14. 14. <ul><li>Can have it right away. </li></ul><ul><ul><li>10 to 15 minutes. </li></ul></ul><ul><ul><li>(Don’t have to wait two weeks for a hearing aid.) </li></ul></ul>Hear better faster. <ul><li>Fitted right the first time – fine-tuned in the first office visit. </li></ul>
    15. 15. You can hear on the phone . <ul><li>Occluding hearing aids tend to produce feedback or “buzz” when used while on the phone. So users often take them out. </li></ul><ul><li>No such problem with RIC. </li></ul>
    16. 16. <ul><li>A setting for a crowded place with background noise, such as a restaurant or cocktail party. </li></ul><ul><li>A setting for a church or auditorium, where you are far from the speaker. </li></ul>
    17. 17. Directional microphones. <ul><li>A “back” microphone reduces distracting noise from behind. </li></ul><ul><li>Amplifies more in the direction you look. </li></ul>
    18. 18. <ul><li>It doesn’t have to be sent off for repairs. </li></ul><ul><li>Instead, it can be replaced off the shelf. </li></ul>Repairs. If there’s a problem with the receiver…
    19. 19. The closest thing to hearing like you did before you needed a hearing aid.
    20. 20. Frequency Compression:
    21. 21. <ul><li>Thresholds 65-70dB or poorer at 2KHz and above. </li></ul><ul><li>Greater than 35dB per octave slope. </li></ul><ul><li>Poor tonal perception </li></ul><ul><li>Hearing loss due to ototoxicity. </li></ul><ul><li>Reduced speech recognition scores. </li></ul><ul><li>Inability to detect and/or recognize /s/, /sh/. </li></ul>Who is a candidate for frequency compression? -10 0 dB 10 20 30 40 50 60 70 80 90 100 110 120 250 500 1000 2000 4000 8000Hz Damaged or dead regions
