Measurements of the longitudinal ultrasonic velocity and the attenuation along the x-, y-and zaxes have been carried out in DBPI single crystals in the vicinity of the ferroelectric phase transition. Regardless of the weakness of elastic anomalies at T c the ultrasonic behaviour in DBPI can be expla
