 Welcome to HTL home page and welcome to Nikko!

　To be a "A HEARING AID TAILOR" is my perpetual target based on
　the orthor's original(*) precise fitting procedure, and to provide a
　more reasonable and lower cost of hearing.

　

＊THE MOST PRECISE HEARING AID FITTING PROCEDURE
　　　"DRF-SSM" …THE ONLY ONE FITTING FORMULA FOR ALL AUDIOGRAM
　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　(Since 1980)

Imformation 　 XXXXXXX 　 XXXXXXX；"SS Zone" 　　　　Estimated SS (Speech Spectrum) Zone (1m) 　 XXXXXXX 　 XXXXXXX；"Modified SS Zone" 　　　　Modified SS Zone by the user's hearing aid (1m) 　"U--U--U"　The user's UCL of hearing (left ear) 　 XXXXXXX 　 XXXXXXX 　The user's dynamic range of hearing 　 XXXXXXX 　"X--X--X" The user's threshold of hearing	DRF-SSM means.. 　Dynamic Range Fitting 　Speech Spectrum 　　　　　　　　Matching  Left data shows a speech banana fitted  skilfully in the wearer's dynamic range  of hearing after fitting.  MPO doesn't exceed his UCL of hearing.   A normal audiogram sheet is used in the  fitting stage. Analyzing a hearing aided  threshold is the most important data for  more precise fitting.  I think a clear hearing　means a "flatten  hearing aided threshold curve" along SS  zone. 　DRF-SSM fitting procedure leads into it 　automatically. Influences of ear size and 　cavity are also corrected automatically. 　　　　　　　　　　　　→see box DRF-SSM  Following data shows author's fitting.... 　　*Japanese version→結果１、 結果２ 　　*English version 　　　　　　　→FOR A PECULIAR AUDIOGRAM  A precise fitting needs much time over two  hours. Hoever,it makes an easy recognition  an effect of tone and MPO controll.  An ideal fitting is made for the individual   audiogram finally. It also reduces a tire  some fitting time for the customer.  *It shows dramatically.→ See under fig.↓
WRONG FITTING? 　　 　A linear analogue BTE; 　HELL; NOISY & UNCOMFORTABLE 　She was suffering from an over heavy and 　unclear hearing. Too loud MPO (exceeded 　her UCL) would have hurt her ear.  She couldn't adapt her hearing aid over  three months.	IMPRESSIVE HEARING? 　　　　 　A digital non linear BTE; 　PARADISE!;CLEAR & NATURAL & COMFORTABLE 　The test BTE's natural and clear sound 　surprised her. She also could feel very 　loud sound simply loud. 　She adapted her test BTE instantly.
A FIVE YEAR'S CHANGING OF 　 HER "HEARING AIDED THRESHOLD" 　　 　STABLE HEARING AND MORE 　 The bold color line shows a hearing- 　aided　threshold. Black and blue thre 　shold curve is obtained by a standard 　BTE(IN1CP). 　 The data are gotten her first BTE 　with a great impression. 　 A red threshold curve is obtained by a 　semi high-end rechargeable BTE in Mar'21. 　Every data suggests a good fitting, but 　the impression isn't the same each other. 　 The newest hearing aids are fitted 　instantly and she got a great joy 　beyond her description.	A DESIGNING OF HER NEWEST HEARING 　AID IS TO * 　　*IMPROVE HEARING INTO A MORE 　　"FLATTEN HEARING UNDER 30dBHL 　　(AIDED THRESHOLD)CURVE. 　　*IMPROVE HEARING IN A NOISY 　　ENVIROMENT. 　 Selected her hearing aid and her 　 ear mold data showes below. (*) 　* AH7MNRTR＋"P"receiver (The first BTE 　 sold in Japan;see below) 　* VENTED(TRENCH TYPE) EAR MOLD 　　　 　RESULT(according to her comments) 　* Her hearing in a noisy environ 　　ment was improved dramatically. 　* Her hearing in a high frequency 　　zone was also improved.
RECORD BREAKNG CASE? 　　IT'S JUST LIKE AS A "CLIFF"! 　 　He was suffering from a catching 　voice because of his "Ski-slope 　audiogram". The slope is very 　steep jsut like as a cliff! 　His former hearing aid(CIC) can't 　correct his hearing reasonably. 　So, he only can hear a lower 　element of voice.	BREAKE THROUGH HEARING! 　　　Results by a test BTE. 　Now, he can catch a whispering(*) 　through his newly fitted hearing 　aid (BTE), as a result of a high 　frequency shift sysytem. (*50cm) 　Bold red line shows his hearing 　aided threshold enabled to catch 　a 50cm aparted whispering. 　Bold gray line shows a threshold 　without BTE. 　　　　(Tested on a 1/3 band noise) 　He is sure to get a more impressive 　hearing after a several remote 　fitting by the author.The procedure 　never stop until he agrees. 　 *We must know a high-performance 　 feedback suppressor successfully 　 supported this fitting procedure. 　　　　　　　　　　　　 ('23/10/15) 　＊CHECK OTHER FITTING CASE？ 　　 Go ⇒ A PECULAR RESPONCE
