1. An acoustic device, comprising:
a microphone array configured to acquire an environmental noise;
a processor configured to:
obtain a sound field estimation by estimating a sound field at a target spatial position using the microphone array, wherein the target spatial position is closer to an ear canal of a user than each microphone in the microphone array, and
generate a noise reduction signal based on the environmental noise and the sound field estimation of the target spatial position; and
at least one speaker configured to output a target signal based on the noise reduction signal, the target signal being used to reduce the environmental noise.
