An apparatus comprising: a length of tubing (502, 1000) configured to physically couple, at a proximal end (504, 1002) of the tubing, to an acoustic stimulation generator (304, 514) configured to generate sound waves representative of acoustic stimulation used to obtain an audiometric measurement with respect to a patient, the tubing providing a first portion of a sound propagation channel (306, 516, 706, 1008) from the acoustic stimulation generator to an ear canal of the patient; an ear tip (308, 508, 700) configured to be disposed at the ear canal of the patient, the ear tip including: an external portion (510, 704) configured to interface with the ear canal of the patient, and an internal portion (512, 702) implemented as a tubular element and including: a proximal end having a first radius and configured to be coupled to a distal end (506, 1004) of the tubing to provide a second portion of the sound propagation channel, a distal end coupled to the external portion of the ear tip, and a neck disposed near the distal end of the tubular element and configured to provide, by having a second radius smaller than the first radius, strain relief for the external portion of the ear tip as the external portion interfaces with the ear canal and the internal portion flexes in relation to the external portion; and a permanent bend (520, 710, 902, 1006) associated with a coupling between the distal end of the tubing and the proximal end of the internal portion of the ear tip, the permanent bend configured to be disposed immediately outside the ear canal of the patient so as to angle the tubing toward a pinna of the patient without obstructing the sound propagation channel when the ear tip is disposed at the ear canal and coupled to the distal end of the tubing. a length of tubing (502, 1000) configured to physically couple, at a proximal end (504, 1002) of the tubing, to an acoustic stimulation generator (304, 514) configured to generate sound waves representative of acoustic stimulation used to obtain an audiometric measurement with respect to a patient, the tubing providing a first portion of a sound propagation channel (306, 516, 706, 1008) from the acoustic stimulation generator to an ear canal of the patient; an ear tip (308, 508, 700) configured to be disposed at the ear canal of the patient, the ear tip including: an external portion (510, 704) configured to interface with the ear canal of the patient, and an internal portion (512, 702) implemented as a tubular element and including: a proximal end having a first radius and configured to be coupled to a distal end (506, 1004) of the tubing to provide a second portion of the sound propagation channel, a distal end coupled to the external portion of the ear tip, and a neck disposed near the distal end of the tubular element and configured to provide, by having a second radius smaller than the first radius, strain relief for the external portion of the ear tip as the external portion interfaces with the ear canal and the internal portion flexes in relation to the external portion; and an external portion (510, 704) configured to interface with the ear canal of the patient, and an internal portion (512, 702) implemented as a tubular element and including: a proximal end having a first radius and configured to be coupled to a distal end (506, 1004) of the tubing to provide a second portion of the sound propagation channel, a distal end coupled to the external portion of the ear tip, and a neck disposed near the distal end of the tubular element and configured to provide, by having a second radius smaller than the first radius, strain relief for the external portion of the ear tip as the external portion interfaces with the ear canal and the internal portion flexes in relation to the external portion; and a proximal end having a first radius and configured to be coupled to a distal end (506, 1004) of the tubing to provide a second portion of the sound propagation channel, a distal end coupled to the external portion of the ear tip, and a neck disposed near the distal end of the tubular element and configured to provide, by having a second radius smaller than the first radius, strain relief for the external portion of the ear tip as the external portion interfaces with the ear canal and the internal portion flexes in relation to the external portion; and a permanent bend (520, 710, 902, 1006) associated with a coupling between the distal end of the tubing and the proximal end of the internal portion of the ear tip, the permanent bend configured to be disposed immediately outside the ear canal of the patient so as to angle the tubing toward a pinna of the patient without obstructing the sound propagation channel when the ear tip is disposed at the ear canal and coupled to the distal end of the tubing.
