and control a volume of an ambient sound output from a speaker provided in a device which is worn so as to cover an ear according to the detected biological information, wherein, in a case in which the biological information indicates a state in which a user is concentrated, the processor is configured to reduce the volume of the ambient sound output from the speaker to be lower than a reference volume, and in a case in which a sound satisfying a predetermined condition is acquired, the processor is configured to output a voice or a sound at a volume higher than the reference volume even though the biological information indicates the state in which the user is concentrated. ### Claim 2 (depends on 1) The information processing system according to claim 1, wherein the device is worn on both ears. ### Claim 3 (depends on 2) The information processing system according to claim 2, wherein the device is worn so as to cover an external acoustic opening. ### Claim 4 (depends on 1) The information processing system according to claim 1, wherein, in a case in which the biometric information indicates a change from the concentrated state, the processor is configured to reproduce the ambient sound acquired in the state in which the user is concentrated or checks whether or not the user wants to reproduce the ambient sound. ### Claim 5 (depends on 4) The information processing system according to claim 4, wherein the ambient sound is acquired by a microphone provided in the device. ### Claim 6 (depends on 1) The information processing system according to claim 1, wherein the predetermined condition is acquisition of a voice including a predetermined term or acquisition of a predetermined type of sound. ### Claim 7 (depends on 6) The information processing system according to claim 6, wherein the predetermined term or the predetermined type of sound is a term or a sound indicating danger. ### Claim 8 (depends on 1) The information processing system according to claim 1, wherein, in a case in which the biological information indicates an unpleasant state, the processor is configured to reduce the volume of the ambient sound output from the speaker to be lower than a reference volume. ### Claim 9 (depends on 1) The information processing system according to claim 1, wherein the control of the volume of the ambient sound is performed in a case in which a user selects execution of an operation mode for controlling the volume of the ambient sound. ### Claim 10 (depends on 9) The information processing system according to claim 9, wherein the operation mode for controlling the volume of the ambient sound includes an operation mode that does not use the detected biological information. ### Claim 11 (depends on 9) The information processing system according to claim 9, wherein the operation mode for controlling the volume of the ambient sound includes an operation mode that superimposes the ambient sound on a sound reproduced from the speaker. ### Claim 12 (depends on 1) The information processing system according to claim 1, wherein the biological information is measured by an electrode that comes into contact with a head or an ear of a user. ### Claim 13 (depends on 1) The information processing system according to claim 1, wherein the biological information is measured in a non-contact manner. ### Claim 14 (depends on 1) The information processing system according to claim 1, wherein the information processing system is a computer that is communicably connected to a device worn by a user. ### Claim 15 An information processing system comprising: a processor configured to detect biological information measured at a head; and control a volume of an ambient sound output from a speaker provided in a device which is worn so as to cover an ear according to the detected biological information, wherein, in a case in which the biological information indicates sleep, the processor is configured to stop the output of the ambient sound from the speaker, and in a case in which a sound satisfying a predetermined condition is acquired, the processor is configured to output a voice or a sound at a volume higher than a reference volume even though the biological information indicates sleep. ### Claim 16 (depends on 15) The information processing system according to claim 15, wherein the predetermined condition is acquisition of a voice including a predetermined term or acquisition of a predetermined type of sound. ### Claim 17 A non-transitory computer readable medium storing a program that causes a computer to perform: detecting biological information measured at a head; and controlling a volume of an ambient sound output from a speaker provided in a device which is worn so as to cover an ear according to the detected biological information, wherein, the controlling further comprises, in a case in which the biological information indicates a state in which a user is concentrated, reducing the volume of the ambient sound output from the speaker to be lower than a reference volume, and in a case in which a sound satisfying a predetermined condition is acquired, outputting a voice or a sound at a volume higher than the reference volume even though the biological information indicates the state in which the user is concentrated. ### Claim 18 A non-transitory computer readable medium storing a program that causes a computer to perform: detecting biological information measured at a head; and controlling a volume of an ambient sound output from a speaker provided in a device which is worn so as to cover an ear according to the detected biological information, wherein, the controlling further comprises, in a case in which the biological information indicates sleep, stopping the output of the ambient sound from the speaker, and in a case in which a sound satisfying a predetermined condition is acquired, outputting a voice or a sound at a volume higher than a reference volume even though the biological information indicates sleep.
