1. Sound data is determined in a reverberation
room at an independent sound laboratory,
according to ISO 3741 en ISO 5135
standards.
2. Lw/Oct. (re. 1pW) are sound power levels
for discharge and radiated sound. Values
< 17 dB are indicated by "-".
3. The values for insertion loss L
include end reflection.

4. dB(A), NC and NR index values are sound
pressure levels. Sound pressure levels
< 20 are indicated by "--".
5. The sound pressure levels for discharge
sound include the values for an acoustic
hose in accordance with table 1.
6. Lp values are including a room absorption
do not
