## Questions & Answers

**Q: Are Cearvol devices amplifiers or hearing aids?**
A: Cearvol devices are true OTC hearing aids, not amplifiers. Amplifiers boost all sounds, while Cearvol hearing aids selectively amplify specific frequencies based on the user’s hearing profile, enhancing speech clarity and reducing background noise.

**Q: How can I assess the degree of my hearing loss?**
A: You can assess your hearing loss with Cearvol’s app, which offers an online hearing test in just a few minutes. It generates an audiogram to apply to your hearing aids. We also recommend personalizing settings.

**Q: What type of hearing loss do these hearing aids support?**
A: The Cearvol OTC hearing aids are medical devices used to improve hearing sense for adults 18 and older with perceived mild to moderate hearing loss in both ears. They are not for individuals with severe to profound hearing loss.

**Q: How long will it take to get used to my hearing aids?**
A: Audiologists recommend 3 weeks for your brain to adapt to wearing hearing aids. In week 1, wear your hearing aids for 1-2 hours per day. In week 2, 3-4 hours per day. After 3 weeks, you are ready for 6+ hours per day and get used to them.

**Q: How can I reduce feedback noises like beeping or whistling?**
A: You could try lowering the volume, switching to different ear tips, and upgrading the firmware of hearing aids. Additionally, adjust noise reduction and speech enhancement settings to focus on the sounds you want to hear for an improved experience.
