2. GENTLEsilence LUX 8000 B KaVo GENTLEsilence 8000fascinating silence Noise creates stress and under long term impact it damages the human health. Especially during concentrated work like a dentist does. That‘s why it has always been a challenge for KaVo to reduce the noise level of KaVo turbine handpieces simultaneously to all the other high tech innovations: KaVo development of noise reduction: 1958 : KaVo Borden-Air 58 78 dB(A) 1970 : KaVo Super All-air 618 75 dB(A) 1977 : KaVo SUPERtorque 630 68 dB(A) 1989 : KaVo SUPERtorque 640 65 dB(A) 2001 : KaVo GENTLEforce 7000 62 dB(A) 2005 : KaVo GENTLEsilence 8000 57 dB(A)

3. GENTLEsilence LUX 8000 B KaVo GENTLEsilence 8000fascinating silence Noise level = acoustic pressure + frequency Acoustic pressure (loudness) is measured in Decibel dB (A) and ranges in a progressive scale from 0 to 140 dB (A). 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

4. GENTLEsilence LUX 8000 B KaVo GENTLEsilence 8000fascinating silence Acoustic pressure dB(A) Humans sense a reduction of the acoustic pressure by 8- 10 decibel as a bisection of the loudness SUPERtorque 640 65 dB(A) GENTLEsilence 8000 57 dB(A) present turbines

5. GENTLEsilence LUX 8000 B KaVo GENTLEsilence 8000fascinating silence Noise level = acoustic pressure + frequency Frequency ( tone / sound ) is measured in Hertz (Hz) and describes the vibration frequency ( rise and fall of acoustic pressure ) per second. 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.

6. GENTLEsilence LUX 8000 B KaVo GENTLEsilence 8000fascinating silence In addition to the reduction of the acoustic pressure ( 57 dB(A) ) we also found a solution to eliminate the high- frequency peaks by using a new technology for fixing the ball bearings on the chuck pleasant to the ear – pleasant for the nerves Basic- frequency : 6 kHz

7. GENTLEsilence LUX 8000 B KaVo GENTLEsilence 8000fascinating silence • By using a new technology of ball • bearings with a one-piece inner ring • an extremly well balanced turbine- • cartridge guarantees vibration- free • performance at only 57 dB(A) with a fascinatingly quiet sound- level • KaVo added values: • fascinatingly quiet sound level • vibration- free performance • long-term durability • Repair service by exchange of the • ball bearings is not possible.

15. GENTLEsilence LUX 8000 B KaVo GENTLEsilence 8000 Sensitivity for precision Sensitivity and tactile- feeling through KaVo Plasmatec- coating and optimized material : grip- sleeve made of stainless steel • improved grip - unique handling

16. Basic-material Plasma GENTLEsilence steel sleeve GENTLEsilence LUX 8000 B KaVo GENTLEsilence 8000 Sensitivity for precision KaVo Plasmatec coating-process : PVD - Physical Vapor Deposition Through a light-arch at a temperature of approx. 10,000 0 C the basic material changes his physical aggregate state up to the 4th level – PLASMA. At a temperature of 250 0 – 300 0 C the plasma, which is mixed with inert gas, falls on the surface of the GENTLEsilence sheath. Metal-ceramic surface which is twice as hard as stainless steel
