01 · Continuity
In practice since 1977
Nearly five decades on Long Island. The same hands, the same standards, the same patients returning year after year, many now bringing their grandchildren.
About Sound Hearing
Two doctors,
one rare practice.
Sound Hearing was built around a pairing you won't find down the street: nearly five decades of clinical leadership alongside a doctor who has lived the patient journey from the inside. This is the story of how that came to be, and why it matters for your care.
Jericho, NY
02 · Disciplines
Three specialties, one roof
Audiology, speech-language pathology, and deaf education, practiced in tandem, so what you hear and how you communicate are treated as one connected story.
03 · Lived experience
A doctor who has been the patient
Dr. Engelhardt has worn hearing devices since childhood. He knows the questions you haven't thought to ask, and answers them before you do.
Our story
Forty-seven years and counting.
A practice doesn't last this long by accident. It lasts because the patients keep coming back, and because the care keeps getting better.
