The parameters of Decibel- measurement for turbine hand-pieces are well-defined in norm EN ISO 7785-1. (e.g.: measuring distance 45 cm) Only data, which are measured under this EN ISO- norm are objectively comparable. Threshold of pain 27.12.2018 - © KaVo Dental GmbH

Human ears can sense sounds at frequencies from 16 – 16,000 Hz. We are sensing high frequency sounds as very unpleasant and even painful. Low frequency tones we sense as particularly loud. 27.12.2018 - © KaVo Dental GmbH
