Question

Which law states that the magnitude of a sensation is directly proportional to the logarithm of the physical stimulus producing it?

(a) Beer-Lambert law

(b) Huygens–Fresnel law

(c) Lorentz law

(d) Weber and Fechner’s law

This question was posed to me during an online exam.

I'd like to ask this question from Acoustics topic in division Acoustics and Ventilation of Construction & Building Materials

Answer 1

Correct option is (d) Weber and Fechner’s law

For explanation I would say: Weber and Fechner’s law states that the magnitude of a sensation is directly proportional to the logarithm of the physical stimulus producing it. For example, loudness which corresponds to the magnitude of the sensation is proportional to the logarithm of the intensity of the sound.
