Distribution method for noise control
First Claim
1. A distribution method for noise control, which is used for adjusting the attenuated amount of an upstream signal passing from a machine room'"'"'s end to an user'"'"'s end, comprising the following steps:
- to emit a simulation signal from the user'"'"'s end, wherein the simulation signal will be transmitted to the machine room'"'"'s end through a splitter and a cable TV line;
to receive and measure power of the simulation signal at the machine room'"'"'s end, and through calculation, to obtain the attenuated amount of the upstream signal passing from the user'"'"'s end to the machine room'"'"'s end; and
to adjust the signal attenuated amount of the attenuator provided in the splitter according to the attenuated amount of the upstream signal passing from the user'"'"'s end to the machine room'"'"'s end.

Abstract
The present invention discloses a distribution method for noise control, which is employed to adjust the attenuated amount of an upstream signal passing from the machine room'"'"'s end to a user'"'"'s end. The method is to emit a simulation signal from a user'"'"'s end, and the simulation signal will be transmitted to a machine room'"'"'s end through a cable TV line for calculating the attenuated amount of the upstream signal passing from the user'"'"'s end to the machine room'"'"'s end. Then, the signal attenuated amount of the attenuator can be adjusted according to the attenuated amount of the upstream signal. Therefore, the power of the upstream signal at the user'"'"'s end can be optimal so as to avoid noise interference.
