Visible Speech with the FONIX FP35 Analyzer

The FP35 Visible Speech feature is available with the FP35 Real-ear Option. It allows you to perform real-ear measurements using live voice or an external signal source. During Visible speech testing, the FP35 hearing aid analyzer will show you both the real-time frequency response and the peaked-pulse average response on a Real-ear SPL graph with the patient’s threshold and uncomfortable values. All together, these elements give you a complete picture of the patient’s real-ear response to the input stimulus.


Testing with live voice can be a great tool for use with your hearing instrument fittings. See how the hearing instrument responds to the actual speech of your client, your client’s spouse or family member. Or attach an external CD player or an iPod to your FP35 analyzer to change the input stimulus to use a pre-recorded signal.
