An attachment device for a probe microphone adapted to be utilized in conjunction with the external ear canal of a person having an ear lobe. A housing is adapted to contain the probe microphone and secures the housing in a fixed relationship with respect to the ear lobe of the person. A probe tube is coupled to the housing and is adapted to be coupled to the probe microphone and adapted to be inserted into the external ear canal of the person. A holding mechanism is coupled to the housing and receives the probe tube and slideably secures the probe tube in a repositionably fixed relationship to the housing. In this manner the housing may be secured and positioned with respect to the ear lobe and the probe tube may be slid through the holding mechanism and positioned reliably in the external ear canal. A marker may be attached to the probe tube to reliably mark a particular location along the probe tube for further reference by a user of the attachment device so that the user may mark a particular location along the probe tube with reference to an extrinsic landmark.
