Abstract

Purpose:

To determine the decibel sound pressure levels generated during extracorporeal lithotripsy for salivary stones, and if such lithotriptor noise levels have the potential for acoustic trauma.

Patients and materials:

Minilith SL-1 salivary gland lithotriptor, sound level meter; five patient survey.

Methods:

Decibel measurements were conducted on the lithotripter-generated sounds, using a sound level meter at specific distances from the active element. In addition, a patient survey was conducted as a cross-reference, to enable comparison of predicted results with actual human perception of sound levels.

Results:

Sound levels ranged between 68 and 80 dB during treatment sessions, for both the lithotriptor operator and the patient.

Conclusion:

During routine use, no acoustic trauma is incurred by either the lithotriptor operator or the patient.
