A hearing screener apparatus is provided. The hearing screener includes a housing, a testing probe and an elastic coupler suspending the testing probe from the housing. The testing probe preferably includes a microphone housing having a first end and a second end. A cavity extends longitudinally into the first end of the microphone housing, and a microphone is mounted to the housing adjacent the cavity. An ear tip is fitted onto the first end of the microphone housing for insertion into a patient's ear. The ear tip preferably has a flexible flange arranged at its end to seal within the ear canal of the patient. A further elastic coupler suspends the ear tip assembly from the testing probe. Preferably. the elastic coupler is a number of elastic bands or o-rings distributed to concentrically suspend the probe within the housing. The screener allows the testing probe to be manipulated about all axes and has an isolation body which is also capable of being manipulated relative to the housing. The elastic couplers provide vibrational noise isolation due to movement of the patient and the user.
