Methods and systems for modification of electronic system operation based on acoustic ambience classification are presented. In an example method, at least one audio signal present in a physical environment of a user is detected. The at least one audio signal is analyzed to extract at least one audio feature from the audio signal. The audio signal is classified based on the audio feature to produce at least one classification of the audio signal. Operation of an electronic system interacting with the user in the physical environment is modified based on the classification of the audio signal.

A method includes, in response to a user operation of starting a hearing test, an electronic device separately plays preset audio at a plurality of volumes, where the volumes include a first volume; determines, based on a confirmation operation for the first volume, that a hearing level of a user is a first hearing level corresponding to the first volume; when playing a downlink signal by using a sound-emitting apparatus, collects the downlink signal and an ambient noise signal by using at least one microphone; and adjusts a play volume of the sound-emitting apparatus from a first sound level to a second sound level based on the first hearing level when at least one of the collected downlink signal and the collected ambient noise signal changes.

A modulator circuit may include an integrator circuit and a gain compensation circuit. The integrator circuit may include a first amplifier including an input to receive a signal and an output to provide an inverted signal and a capacitor including a first terminal coupled to the input and a second terminal coupled to the output. The gain compensation circuit may include a second inverter amplifier including a gain input coupled to the output of the first amplifier and including a gain output; a first resistor including a first terminal coupled to the gain output and including a second terminal; and a second capacitor including a first terminal coupled to the second terminal of the first resistor and including a second terminal coupled to the gain input. The integrator circuit has a finite DC gain and the gain compensation circuit is configured to compensate for the finite DC gain.
