Abstract
A headphone volume control method calculates a level of a sound signal, which is captured by a microphone, during a first period, determines a target value of a sound volume based on the above-mentioned level, and gradually changes a reproduction volume of content to be reproduced to the above-mentioned target value over a second period.
Claims14
A headphone volume control method comprising:
- receiving a first sound signal captured by a microphone;
- receiving a second sound signal of content;
- adjusting a sound volume of the second sound signal;
- calculating a first level of a composite signal composing the first sound signal and the adjusted second sound signal during a first period;
- calculating a second level of the received second sound signal during the first period;
- receiving a volume operation from a user;
- setting a reference level based on the first level and the second level, upon receiving the volume operation;
- determining a target value of the sound volume based on the reference level and a level ratio of the first level to the second level;
- and
- changing a reproduction volume of the content to be reproduced to the target value gradually over a second period.

A headphone comprising:
- a microphone;
- a user interface that receives a volume operation from a user;
- and
- at least one processor that implements instructions stored in a memory and executes a plurality of tasks, including:
- a sound receiving task that receives a first sound signal captured by the microphone;
- a sound receiving task that receives a second sound signal of content;
- a sound adjusting task that adjusts a sound volume of the second sound signal;
- a level calculating task that calculates a first level of a composite signal composing the first sound signal and the adjusted second sound signal during a first period;
- a level calculating task that calculates a second level of the received second sound signal during the first period;
- a reference setting task that sets a reference level based on the first level and the second level upon receiving the volume operation;
- a target value setting task that determines a target value of the sound volume based on the reference level and a level ratio of the first level to the second level;
- and
- a level adjusting task that changes a reproduction volume of the content to be reproduced to the target value gradually over a second period.
