A hearing aid comprises a microelectromechanical systems microphone which receives inputs of external sound signals, converting the sound signals to analog signals, and outputting the analog signals; a hearing aid processor chip which converts the analog signals to digital signals, performs gain correction and digital signal processing to the digital signals, and converts the processed digital signals to analog signals; and a microelectromechanical system receiver which outputs the analog signals converted from the processed digital signals as sound signals, wherein the microelectromechanical system microphone is attached to a first surface of the hearing aid processor chip, and the microelectromechanical system receiver is attached to a second surface of the hearing aid processor chip, so that the microelectromechanical system microphone, the hearing aid processor chip, and the microelectromechanical system receiver are integrated as a single body.
