Counseling is an essential part of the client centered hearing aid fitting process. This is where Visible Speech Mapping plays a vital role, as it engages the client with dynamic, graphic examples next to the real-ear measurement information. This is why Visible Speech Mapping is becoming more and more popular with hearing healthcare professionals and their clients.
