The electronic device is configured to generate a signal. The first assistive listening device is configured to detect a first intensity of the signal. The second assistive listening device spaced is apart from the first assistive listening device by a fixed distance and is configured to detect a second intensity of the signal. The electronic device is further configured to generate a distance adjustment signal based on the first and second intensities for adjusting a first distance between the first assistive listening device and the electronic device and adjusting a second distance between the second assistive listening device and the electronic device. ## Claims ### Claim 1 A method for a hearing test, comprising: detecting a first intensity of a signal generated by an electronic device through a first assistive listening device; detecting a second intensity of the signal generated by the electronic device through a second assistive listening device, wherein the first and second assistive listening devices substantially maintain a fixed distance therebetween; and responsive to the first and second intensities detected by the first and second assistive listening devices, selectively adjusting a first distance between the first assistive listening device and the electronic device and adjusting a second distance between the second assistive listening device and the electronic device by moving the electronic device toward a midperpendicular plane of a virtual connection line between the first and second assistive listening devices. ### Claim 2 (depends on 1) The method of claim 1, wherein the signal comprises a pure tone. ### Claim 3 (depends on 2) The method of claim 2, wherein responsive to the first and second intensities detected by the first and second assistive listening devices, selectively adjusting the first and second distances comprises: comparing the first and second intensities detected by the first and second assistive listening devices. ### Claim 4 (depends on 2) The method of claim 2, wherein the signal comprises a testing sound that includes a plurality of sounds of different frequencies respectively. ### Claim 5 (depends on 4) The method of claim 4, wherein responsive to the first and second intensities of the testing sound detected by the first and second assistive listening devices, selectively adjusting the first and second distances comprises: determining whether the first and second intensities of the testing sound detected by the first and second assistive listening devices are within an intensity region; and further determining whether a volume of the testing sound generated from the electronic device reaches a volume output boundary. ### Claim 6 (depends on 5) The method of claim 5, wherein the intensity range is in a range from about 50 dB to about 80 dB. ### Claim 7 (depends on 5) The method of claim 5, wherein if the first and second intensities of the testing sound detected by the first and second assistive listening devices are not within the intensity region and the volume of the testing sound generated from the electronic device does not reach the volume output boundary of the electronic device, adjusting the volume of the signal generated from the electronic device until the first and second intensities of the testing sound detected by the first and second assistive listening devices are within the intensity region. ### Claim 8 (depends on 5) The method of claim 5, wherein if any one of the first and second intensities of the testing sound detected by the first and second assistive listening devices are not within the intensity region and the volume of the testing sound generated from the electronic device reaches the volume output boundary of the electronic device, adjusting a third distance between a position center and the electronic device until the first and second intensities of the testing sound detected by the first and second assistive listening devices are within the intensity region, wherein distances from the position center to first and second assistive listening devices are substantially equal, and a distance from the position center to the first assistive listening device is about half a distance between the first and second assistive listening device. ### Claim 9 A method for a hearing test, comprising: detecting a first intensity of a signal generated by an electronic device through a first assistive listening device; detecting a second intensity of the signal generated by the electronic device through a second assistive listening device, wherein the first and second assistive listening devices substantially maintain a fixed distance therebetween; and responsive to the first and second intensities detected by the first and second assistive listening devices, selectively adjusting a first distance between the first assistive listening device and the electronic device and adjusting a second distance between the second assistive listening device and the electronic device by rotating the first and second assistive listening devices relative to the electronic device to an angle based on a center rotating axis, wherein the center rotating axis is substantially located between the first and second assistive listening devices. ### Claim 10 (depends on 9) The method of claim 9, wherein when the first intensity of the pure tone is lower than the second intensity of the pure tone at the first and second assistive listening devices, rotating the first assistive listening device toward the electronic device to the angle. ### Claim 11 (depends on 9) The method of claim 9, wherein when a difference between the first and second intensities of the pure tone at the first and second assistive listening devices is in a range from about 5 dB to about 9 dB, rotating the first and second assistive listening devices about 30 degree. ### Claim 12 (depends on 9) The method of claim 9, wherein when a difference between the first and second intensities of the pure tone at the first and second assistive listening devices is in a range from about 10 dB to about 15 dB, rotating the first and second assistive listening devices about 60 degree. ### Claim 13 (depends on 9) The method of claim 9, wherein when a difference between the first and second intensities of the pure tone at the first and second assistive listening devices is greater than about 16 dB, rotating the first and second assistive listening devices about 90 degree. ### Claim 14 (depends on 9) The method of claim 9, wherein when a difference between the first and second intensities of the pure tone at the first and second assistive listening devices is less than a lower limit, maintaining the angle between the first and second assistive listening devices and the electronic device. ### Claim 15 (depends on 14) The method of claim 14, wherein the lower limit is about 4 dB.
