Various systems and methods are provided for conducting acoustical measurements via an inflatable mannequin. In one embodiment, a system comprises an inflatable mannequin that comprises a detachable mannequin head, a plurality of inflatable anatomical parts, and a plurality of configurable joints, an inflation system that calibrates and controls inflation of the plurality of anatomical parts of the inflatable mannequin; and a joint control system that calibrates and controls the plurality of configurable joints via joint motors. In another embodiment, a first method comprises selecting a mannequin profile based on sizes of anatomical parts of the inflatable mannequin and second method comprises conducting acoustical measurements with the selected mannequin profile. In this way, acoustical measurements may be conducted to develop audio processing schemes that widen the sweet spot in an interior of a vehicle.

Provided is a hand emulator and an acoustic testing system. The hand emulator includes: a main support configured to support a device under test, the main support includes a palm, a thumb, an index finger, a middle finger, a ring finger and a little finger that are movably arranged at an end of the palm; a stopper including a plurality of limit pillars, at least some of the plurality of limit pillars are arranged on the palm, several limit pillars of the plurality of limit pillars enclose to form an accommodating space, and the device under test is limited within the accommodating space. The hand emulator can measure the frequency response of the speaker and/or the microphone of the device under test, emulate acoustic characteristics similar to the user's hand, and accurately and repetitively position the device under test, which improves existing measurement standards and creates new testing methods.
