The MAX5407 SOT-PoT is a logarithmic taper digital potentiometer with 32 tap points that has 1dB steps between taps. This device is ideal for audio applications, such as volume control and fading/balancing audio signals. The MAX5407 consists of a res
Logarithmic Scales in Acoustic Spectra: Decibels and ...
https://demonstrations.wolfram.com/LogarithmicScalesInAcousticSpectraDecibelsAndOctaves/
In acoustics huge changes in measurable physical parameters (pressure power frequency) correspond to relatively small changes in perceived properties (loudness pitch). Simply using a linear scale is impractical since the variation gives an inadequate guide to the perceived sound. Instead it is more practical to convert to logarithmic scales.

1 Theory and Applications of Logarithmic Amplifiers The theory and construction of these circuits are actually readily understood. Figure 1 shows an amplifier that provides a logarithmic output for a linear input current or voltage. For input currents, the circuit will maintain 1% logarithmic conformity over almost six decades of operation.

Potentiometers: Audio vs. Linear Tapers
https://www.jameco.com/Jameco/workshop/circuitnotes/Potentiometers-audio-taper-vs-linear.html
Non-linear tapers are often referred to as a logarithmic or audio taper. These are most commonly used for audio volume control. The human ear is sensitive to sound intensity in a logarithmic fashion, meaning at low sound intensities a small change in intensity is perceived as a big change in loudness, while at high intensities a large change in ...

Integrated DC Logarithmic Amplifiers. Abstract: Among the classes of logarithmic amplifiers, the DC log amp continues to be a very powerful, cost-effective solution for compressing wide-dynamic-range sensor signals. This article derives the overall DC log amp transfer function from the VBE-to-IC transfer characteristic of bipolar transistors.
