戴助聽器常遇到的問題
1.如何佩戴助聽器?
初次使用助聽器您也許會覺得聲音不夠真實清晰。因為您已經習慣瞭原來的聽力狀況,當使用助聽器後,聽到的是些不熟悉的聲音,因此一時不能適應。解決問題的主要方法是進行必要的適應性訓練,剛開始佩帶的時間不要太長,音量不要過大,慢慢適應。
2.如何進行適應性訓練?
助聽器適應性訓練並不復雜,總的原則是堅持戴用、分步適應：
(1)從每日戴用時間上講,宜從短到長;
(2)從音量調節上看,宜先小後大;
(3)從交際環境說,宜先安靜後曹雜、先簡單後復雜。
如此循序漸進,才能使您盡快渡過適應期,使助聽器的作用最大限度地發揮出來。
3.戴用助聽器為何會產生嘯叫?
耳塞與耳道接觸部位封閉不嚴,放大的聲音從縫隙中泄露出來又返回到麥克風再次被放大.就會產生嘯叫。這種現象類似於我們常見的麥克風靠近音響時出現嘯叫聲那樣。
(1)手或某個物件靠近助聽器，因為部分聲音反射在手掌或物件上又傳回麥克風進一步放大所致。
(2)助聽器沒有完全塞入耳道或與耳道壁密封不緊，放大後的聲音泄露並傳回麥克風所致。
(3)耳內有大量的耳屎，發生耳屎栓塞，放大後的聲音反射到耳屎上再次傳給麥克風，也將產生反饋。
4. 怎樣避免嘯叫?
(1)先將助聽器音量調節旋鈕調到“1”的位置，然後將耳塞塞入耳內並盡量塞緊，再將音量調到最清晰位置。
(2)如果耳塞無法塞緊請換另一個比較合適的耳塞試試，塞緊耳朵,不要泄漏空氣。
