The longitudinal ultrasonic velocity and attenuation in ferroelectric telluric acid ammonium phosphate (TAAP) along the direction perpendicular to the (101) face has been measured across the Curie temperature at 10, 30 and 50 MHz. A pronounced anomaly in ultrasonic attenuation is observed at 50MHz near the Curie temperature. The ultrasonic velocity exhibits a slope variation at the transition temperature.
