The invention discloses a sound wave wall and a design method thereof; the sound wave wall is arranged in a boundary area of an antique place setting scope, and comprises at least two support layers, wherein shapes and structures are the two support layers are same; a sound source is arranged in a corresponding position of each support layer; the support furthest away from a selected place is provided with a ultrasonic sensor; when an object is detected to enter a preset scope of the selected place, the ultrasonic sensor can send a detection signal to a microprocessor, and the microprocessor can send an alarm signal to an alarm device; the sound source on the support closest to the selected place can firstly form shock waves, and the shock waves can propagate along the support further away from the selected place; the sound sources on other supports make no action; when the shock waves arrive at the next support, the sound source on the next support can form shock waves, the newly formed shock waves are stacked with the arrived shock waves, and then propagate along the supports further away from the selected place; when the shock waves arrive at the remotest support from the selected place, the object is blocked to enter the selected place.
