What is In Situ?
In situ is a Latin term that means “in place” or “in the natural position.” In audiology, the term in situ is used to refer to measurements that are made with the hearing aid in place in the ear. This is in contrast to measurements that are made with the hearing aid removed from the ear, which are referred to as out situ measurements.
In situ measurements are more accurate than out situ measurements because they take into account the acoustic properties of the ear canal.
What does out situ mean?
Out situ is a Latin term that means “out of place” or “not in the natural position.” In audiology, the term out situ is used to refer to measurements that are made with the hearing aid removed from the ear. This is in contrast to measurements that are made with the hearing aid in place in the ear, which are referred to as in situ measurements.
What are the Different Types of Hearing Aid Feedback?
There are two main types of hearing aid feedback: acoustic feedback and occlusion feedback. Acoustic feedback occurs when sound from the hearing aid microphone is amplified and then picked up by the hearing aid receiver. This can cause a high-pitched squealing sound. Occlusion feedback occurs when the ear canal is blocked, such as by a hearing aid earmold or by the user’s finger. This can also cause a high-pitched squealing sound.
What is Immittance in Audiology?
Immittance is a measure of the acoustic properties of the ear. It is used to assess the function of the middle ear, which is the part of the ear that helps to transmit sound to the inner ear. Immittance measurements can be used to diagnose hearing loss, middle ear disorders, and ear canal problems.
What Level of Hearing Loss Requires a Hearing Aid?
There is no one-size-fits-all answer to this question, as the level of hearing loss that requires a hearing aid will vary from person to person. However, in general, people with mild to severe hearing loss may benefit from using a hearing aid.
If you think you may have hearing loss, it is important to see an audiologist for evaluation.
