I have heard that the shock wave applicator (lithotripter) in the urology department is noisy and there is a need to wear ear protection. Is it required during cardiac applications?

No. Unlike urologic applications, Cardiac shock wave therapy requires less powerful shock waves (1/10th of Lithotripsy). For that reason the Cardiospec is fitted with a smaller generator, producing less intense electrical sparks thus generating significantly less noise. There is no need to wear ear protection during treatment.
