1. A method, comprising:
receiving inputs into a digital twin, the inputs including sound information from a microphone array deployed in an environment;
performing sound quality operations based on the inputs by the digital twin, wherein the digital twin includes a digital copy of the microphone array;
generating outputs of the sound quality operations.
 
19. A non-transitory storage medium having stored therein instructions that are executable by one or more hardware processors to implement a digital twin of a physical device, the digital twin comprising:
an input configured to receive noise source data, background noise, movement trajectory, array parameters, room acoustic parameters, and a sound propagation model;
functions including data retrieval functions, optimization functions, simulation functions, sensing functions, performance prediction functions, and remote monitoring functions;
an output configured to generate outputs including a sound map, real-time data visualization, optimized array patterns and parameters; speech intelligibility, signal to noise ratio, and sound quality.
