At present, small hearing aids and high-power hearing aids on the market can hardly avoid howling.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch2\u003e\u003cspan style=\"color:rgb(244, 78, 59)\"\u003e\u003cstrong\u003eWays to avoid howling\/noise:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\u003cp\u003e1. When the power is high (the amplified sound is large), howling is more likely to occur. Therefore, gradually increasing the volume from low can effectively avoid howling.\u003c\/p\u003e\u003cp\u003e2. When the ear canal is completely sealed, there is no howling sound. Therefore, please use hearing aids after cleaning your ear canal, and test the earplugs from large to small to find the most suitable earplugs.\u003c\/p\u003e\u003cp\u003e3. After the hearing aid enters the ear canal, it is recommended to push the hearing aid with your fingers hold it for 1-2 seconds, and then release it to fully extend the earplug.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch2\u003e\u003cstrong\u003e\u003cspan style=\"color:rgb(244, 78, 59)\"\u003eKindly Remind\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h2\u003e\u003cp\u003e1.
