The required sound attenuator insertion loss is the difference between the calculated path and the target background noise level. [16] If no attenuator selection is feasible, the noise control engineer and mechanical must re-evaluate the path between the equipment and the sound attenuator.
In electronics, crosstalk is a phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel.

The L pad attenuates the signal by having two separate rheostats connected in an "L" configuration (hence the name). One rheostat is connected in series with the loudspeaker and, as the resistance of this rheostat increases, less power is coupled into the loudspeaker and the loudness of sound produced by the loudspeaker decreases.
This is a list of tables showing the historical timeline of the exchange rate for the Indian rupee (INR) against the special drawing rights unit (SDR), United States dollar (USD), pound sterling (GBP), Deutsche mark (DM), euro (EUR) and Japanese yen (JPY). The rupee was worth one shilling and sixpence in sterling in 1947.
A price signal is information conveyed to consumers and producers, via the prices offered or requested for, and the amount requested or offered of a product or service, which provides a signal to increase or decrease quantity supplied or quantity demanded.
An attenuator is a passive broadband electronic device that reduces the power of a signal without appreciably distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than unity. An attenuator is often ...
