In 1980, Hemanta had a heart attack that severely affected his vocal capabilities, especially his breath control. He continued to record songs in the early eighties, but his voice was a shade of its rich baritone past. In 1984, Hemanta was felicitated by different organizations, most notably by the Gramophone Company of India, for completing 50 years in music. That very year Hemanta released his last album with Gramophone Company of India — a 45 rpm extended play disc with four non-film songs. Over the next few years, Hemanta released few non-film songs for small-time companies that had cropped up in the nascent cassette-based music industry. Only a few of these were commercially successful. He composed music for a handful of Bengali movies and one Bengali and one Hindi tele-series. However, by this time he had become an institution, a beloved and revered personality who was a courteous and friendly gentleman. His philanthropic activities included running a homeopathic hospital in memory of his late father in their native village in Baharu, in the South 24 Parganas district of West Bengal. He continued to feature regularly on All India Radio, Doordarshan (TV) and live programmes/concerts during this period.
