1. An apparatus comprising:
- a housing configured to be positioned in a user'"'"'s ear;
a loudspeaker located at a first position within the housing and configured to provide an acoustic signal;
a microphone located at a second position within the housing configured to detect an acoustic signal wherein the second position is different from the first position so that the microphone is positioned between the loudspeaker and a ear drum, wherein the acoustic signal provides an indication of acoustic characteristics of the user'"'"'s ear and/or an amount of leakage between the housing and the user'"'"'s ear;
a filter configured to filter an input signal provided to the loudspeaker; and
a controller configured to use an electrical signal provided by the microphone, based on the acoustic signal, to be used to provide a control signal for controlling the filter to determine an output for the loudspeaker.

13. A method comprising:
-
providing an acoustic signal towards an ear drum from a first position; detecting an acoustic signal at a second position where the second position is displaced from the first position so that a microphone is positioned between a loudspeaker and the ear drum and the first position; using the detected acoustic signal to provide a control signal to a filter for filtering an input signal and outputting a target output to the loudspeaker, wherein the target output is unique to a user'"'"'s ear and the position of an apparatus within the user'"'"'s ear. - View Dependent Claims (14, 15, 16)

17. A non-transitory computer readable medium storing a program of machine-readable instructions executable by a digital processing apparatus of a computer system to perform operations for controlling computer system actions, the operations comprising:
-
providing an acoustic signal towards an ear drum from a first position; detecting an acoustic signal by a microphone at a second position where the second position is displaced from the first position so that the microphone is between a loudspeaker and the ear drum; and using the detected acoustic signals to provide a control signal to a filter for filtering an input signal and outputting a target output to the loudspeaker, wherein the defined target output is unique to a user'"'"'s ear and the position of the apparatus within the user'"'"'s ear. - View Dependent Claims (18, 19)
