Some hearing aids come with vents already built in, while others require the addition of a vent. Vents can also affect the frequency response of the hearing aid.
What do vents do on a hearing aid?
Vents are holes that are placed in hearing aids or earmolds to modify the amount of occlusion effect noted by a hearing aid wearer or to adjust the frequency response of the hearing aid.
What is a common reason for venting a hearing aid?
The most common reason for venting a hearing aid is to reduce the occlusion effect. The occlusion effect is a phenomenon that occurs when a hearing aid is sealed in the ear canal. This can cause the wearer to hear their own voice louder than it actually is, which can be annoying and make it difficult to understand speech. Venting the hearing aid allows some air to flow in and out of the ear canal, which reduces the occlusion effect.
What is an earmold vent?
An earmold vent is a hole that is placed in an earmold. Earmold vents are used for the same reasons as hearing aid vents. They can be used to reduce the occlusion effect, adjust the frequency response of the hearing aid, or to allow moisture to escape from the ear canal.
What is IROS vent on a hearing aid?
IROS stands for “Invisible Retrofit Open Sound.” It is a type of vent that is placed in the shell of a hearing aid. IROS vents are very small and are not visible to the naked eye. They are used to reduce the occlusion effect and to improve the sound quality of the hearing aid.
