⚠️ Why Hearing Aids Howl (High-Pitched Whistling)
Understanding the science & solving it simply

-1 The Feedback Loop Explained:
Hearing aids naturally amplify sound, but when:
1️⃣ Poor Seal = Ear canal & earplug mismatch
2️⃣ Sound Escape = Amplified sound leaks out
3️⃣ Re-Amplification = Microphone picks up escaped sound→ Creates continuous loop → Sharp feedback (howling)

-2 💡 Proven Solution:
Your kit includes 4-size earplugs - find your perfect match:

1. Test sizes starting from smallest
2. Ideal fit = Snug seal without discomfort
3. Howling stops = Success!

-3 Bonus Tip:
✅ Always insert fully before powering on
✅ Re-test fit if howling returns (ear canal shape changes seasonally)

5.  Power Management

• 🟢 On: Activate after full insertion to prevent feedback
• 🔴 Off: Switch to OFF position when not in use
