Key Takeaways Open domes allow natural sound to pass through, which is ideal for perceived mild to moderate hearing loss. Closed domes provide better amplification, making them more suitable for moderate to severe hearing loss. Open domes offer a more natural sound experience and reduce the occlusion effect, while closed domes enhance low-frequency sounds but may cause a sense of fullness or discomfort. Open domes are best for quieter settings, while closed domes block ambient noise and are suitable for noisy environments. Nano’s Audacity RIC hearing aids come with both open and closed dome options, allowing users to customize their experience for different environments.

Closed domes provide better amplification by blocking more of the ear canal - they are thus better suited for greater hearing loss and noisier environments. Open Hearing Aid Domes Design and Function Open domes have small openings that allow ambient sounds to enter the ear canal, reducing the occlusion effect, where your voice sounds boomy or echoey. They are often recommended for individuals with perceived mild to moderate hearing loss. Open Dome Benefits Natural sound experience Reduced occlusion effect Comfortable for extended wear Open Dome Drawbacks Less effective for severe hearing loss May not block background noise effectively Closed Hearing Aid Domes Design and Function Closed domes have fewer and smaller openings, blocking more ambient noise for a clearer, more focused sound.

Shop NANO OTC Hearing Aids Frequently Asked Questions (FAQs) What is occlusion in hearing aids? Occlusion occurs when your voice sounds boomy or echoey because the ear canal is blocked by the hearing aid dome. Open domes reduce this effect by allowing more natural sound to enter, whereas closed domes can increase the sensation of occlusion due to their tighter seal. Are open domes suitable for severe hearing loss? No, open domes are not recommended for severe hearing loss. They allow too much natural sound to enter, which can interfere with amplified sound. Closed or power domes are better suited as they provide better amplification and block more ambient noise. How often should I replace my hearing aid domes? Replace hearing aid domes every few months, depending on usage and care. Signs for replacement include visible wear, reduced sound quality, and discomfort. Regular maintenance extends their life, but timely replacement is key for optimal performance. Can I switch between open and closed domes? Yes, some hearing aid models allow you to switch between open and closed domes based on your needs. Open domes are ideal for natural sound in quiet environments, while closed domes offer better amplification in noisy settings. Do open domes affect battery life? Open domes generally do not significantly affect battery life. However, because they allow more natural sound to enter the ear, you may adjust the volume more frequently, which can impact battery usage. Closed domes provide better amplification and may result in more consistent battery consumption. How do I know if my dome fits properly? A properly fitting dome should feel comfortable and secure in your ear canal without causing discomfort. You should not experience any whistling or feedback, and sound quality should be clear. Are there other types of domes apart from open and closed? Yes, there are other types of domes such as tulip and power domes. Tulip domes are a hybrid between open and closed, providing a balance of natural sound and amplification. Power domes create a complete seal in the ear canal, offering maximum amplification for severe hearing loss. Why Should I Choose Nano OTC Hearing Aids?
