How to determine if the sound of a child’s hearing aid is appropriate

To verify the suitability of the hearing aid adjustment, objectively, we have four main methods to verify the effect of hearing aid debugging.


1. Hearing aid threshold assessment: Verify the size of the hearing aid sound by waving the smallest sound that can be heard after wearing the hearing aid. This is one of the most widely used verification methods.

2. Questionnaire evaluation: refers to whether the hearing aid after the fitting can achieve the desired effect. The audiologist needs to make a subjective judgment through the standardized questionnaire on the patient’s benefit effect and final effect. This method is used more abroad.

3. Speech test: After reading a hearing aid, play a recorded vocabulary through headphones or audio. This watch is divided into single syllables, two syllables and short sentences. When the user hears a vocabulary, he repeats and records the correct number and the number of errors. Speech test in hearing aid fitting can help us to accurately understand whether the volume of the adult hearing aid is appropriate during speech communication, whether the parameters of the hearing aid are properly debugged and set, what effect can we achieve after wearing the hearing aid, if the effect is not ideal, we should How to improve our verbal communication skills and so on. Therefore, speech testing has become an integral part of our adult hearing aid fitting.

4. Real ear analysis: It is based on the difference of each ear can be personalized and accurately adjusted by professional real ear analysis instruments. Conventional hearing aid fitting is only done after hearing aid sound field test or by asking subjective feelings, debugging, debugging error is large, patient satisfaction is low, and patients with external and middle ear malformations and external middle ear surgery are even worse. Therefore, to achieve accurate fitting, it is necessary to combine the real ear test to achieve the target of the actual output of the hearing aid. Studies have shown that the true ear test evaluates the accuracy of the gain at3dBAnd the sound field functional evaluation gain is about15dBIt can be seen that the real ear test is the most accurate means for evaluating the amplification effect of hearing aids. For children, the real ear test and behavioral function verification can be worn.

5.For young children, the size of the hearing aid sound cannot be expressed autonomously. We can verify it by sound field test. In a silent sound field environment, the effect of the baby’s hearing aid is verified by giving the sound game. The average child is tested by the method of real ear test during the fitting, and the test by the sound field test method can basically determine the wearing effect of the hearing aid!
