Techniques and apparatuses are described that implement hand-grip location detection using ultrasound. In particular, an ultrasonic sensor determines a location that a user's hand grips a user device. While gripping the user device, the hand creates an additional aperture area, which amplifies ultrasonic signals that are received by one or more transducers of the ultrasonic sensor that are proximate to the user's hand. By analyzing the amplitude (or power) of received ultrasonic signals, the ultrasonic sensor can detect if the user's hand is proximate to a particular transducer. In some implementations, the ultrasonic sensor utilizes speakers and / or microphones that are present within the user device. In this way, the ultrasonic sensor can have a relatively small footprint and fit within space-constrained devices.
