Carl Geisz, sales manager at Envoy, said one advantage of the Esteem’s design is that it uses the patient’s eardrum as the microphone, letting the system take full advantage of the natural acoustics of the outer ear and, therefore, delivering a more natural sound.
Four Iranian scientists recently published the results of a clinical trial of Envoy Medical’s Esteem middle ear system in an article in European Archives of Otorhinolaryngology, which appeared online on Feb. 17. Lead author Faramarz Memari, MD, who is on the faculty of the department of otorhinolaryngology at the University of Medical Sciences and Health Services in Tehran, noted that while the 10 subjects experienced gain similar to that experienced with their own conventional aids, they reported better subjective hearing quality.
“Some patients who did not have better thresholds in their post-op audiogram compared with their hearing aids were still very happy,” he said in an interview with ENT Today. “One patient stated that he hated washing dishes while using conventional hearing aids, because the sound of dishes bothered him. But now he enjoys washing dishes because that sound doesn’t bother him and instead he can hear the sound of water running very well.”
