How to Build a Simple Attenuator Circuit
http://www.learningaboutelectronics.com/Articles/Attenuator-circuit.php
Attenuator Circuit Schematic Diagram. The circuit we will build is shown below: Here we are using the potentiometer as an attenuator for the buzzer sounds. Because this is for audio sounds, the best potentiometer to use is a log taper or audio potentiometer.

Summary: Attenuators. An attenuator reduces an input signal to a lower level. The amount of attenuation is specified in decibels (dB). Decibel values are additive for cascaded attenuator sections. dB from power ratio: dB = 10 log10(PI / PO) dB from voltage ratio: dB = 20 log10(VI / VO) T and Π section attenuators are the most common circuit configurations.

0 – 44 dB RF attenuator Schematic Circuit Diagram. Anyone who has to reduce the amplitudes of RF signals in a controlled manner needs an attenuator. Linearly adjustable attenuation networks using special PIN diodes are available for this, but they require quite intricate control circuitry. A simpler solution is to use an integrated attenuator ...
Audio Volume Control Attenuator with IR Control
http://electronics-diy.com/audio-volume-control-attenuator-with-ir-control.php
The circuit provides both audio volume and input channel selection. A stepwise volume control is implemented with a set of small relays and resistors. In a high-end audio system, a noticable sound improvement over potentiomeneters can be obtained, also over 'audio grade' potentiometers. Clearly, the IR remote control provides convenience over solutions with …
