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.
Minilith SL-1 salivary gland lithotriptor, sound level meter; five patient survey.
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.
Sound levels ranged between 68 and 80 dB during treatment sessions, for both the lithotriptor operator and the patient.
During routine use, no acoustic trauma is incurred by either the lithotriptor operator or the patient.
确定唾液腺结石体外冲击波碎石术期间产生的分贝声压水平，以及这种碎石机噪音水平是否存在造成声创伤的可能性。
Minilith SL - 1唾液腺碎石机、声级计；五项患者调查。
使用声级计在距有源元件特定距离处对碎石机产生的声音进行分贝测量。此外，进行了患者调查作为交叉参考，以便将预测结果与人类对声级的实际感知进行比较。
在治疗过程中，碎石机操作人员和患者处的声级范围为68至80分贝。
在常规使用过程中，碎石机操作人员和患者均未遭受声创伤。
