Speech test is a test method that can directly reflect the level of speech recognition ability, and it is a test method to check whether the whole path from the external ear to the auditory system is normal.
Speech audiometry and sound field testing are two different ways. The final effect of hearing aid compensation is determined by two factors. One is whether the hearing aid compensation is appropriate (loudness, frequency, compression, etc. ), and the other is the customer's own speech recognition rate.
True ear analysis refers to all acoustic measurements made on a person's real ear, which can be called true ear analysis or true ear measurement. In the field of hearing AIDS, it refers to the acoustic measurement around the intervention gain near the eardrum of the real ear. If we only rely on the software provided by hearing aid manufacturers without real ear testing, there will be great deviation, which may lead to excessive amplification and damage to the patient's residual hearing, or insufficient amplification, which can not really make good use of the patient's residual hearing and make the hearing aid play its best role. The evaluation of hearing aid effect by real ear analysis is limited to the comparison with the standard value; Clinical response field evaluation, true ear analysis and speech recognition rate evaluation are combined.
