Abstract: Provided are a biological sound measurement device capable of detecting contact with a body surface of a living body with a simple configuration, a control method for the biological sound measurement device, and a non-transitory recording medium storing a control program for the biological sound measurement device. The biological sound measurement device (1) includes: a measuring unit (3) that detects a biological sound of a living body in a state of contact with a body surface S of the living body; and a contact state determination unit (41) that determines whether or not a contact state is active in which the measuring unit (3) is in contact with the body surface S, based on a change in a sound pressure level of sounds detected by the measuring unit (3).
