As an example, we will calculate step by step the
attenuation from the socket in Bedroom 2 on the
2nd fl oor:
Metres of cable T100 5+1+7 = 13 metres of cable
Frequency
Attenuation
20
3.5 + 9.5 + 13x0 + 0.6 = 13.6 dB
55.25
4.5 + 8.5 + 13x0 + 0.6 = 13.6 dB
99
4.5 + 8.5 + 13x0 + 0.6 = 13.6 dB
120
4.5 + 8.5 + 13x0 + 0.6 = 13.6 dB
175.25
4.5 + 8.5 + 13x0.08 + 0.6 = 14.64 dB
The theoretical attenuation is calculated in a similar
way in the rest of the installation sockets.
The following table is the result:
