hertz effect: meaning, definition, pronunciation and examples

For sound waves, yes. The 'Hertz effect' is essentially the acoustic Doppler effect, named specifically for Heinrich Hertz who investigated such wave phenomena. The term 'Doppler effect' is more general and universally used today.

The Doppler effect (named after Christian Doppler) is the broader principle applicable to all waves (sound, light). While Hertz made significant contributions to understanding wave behaviour, his name became more strongly associated with electromagnetic waves and the unit of frequency, leaving 'Doppler effect' as the dominant term for the frequency shift phenomenon.

You are most likely to encounter it in historical physics literature, specialised academic papers on the history of acoustics, or in very detailed technical discussions that wish to distinguish the acoustic manifestation from the broader Doppler principle.

For clarity and common understanding, always use 'Doppler effect' (or 'Doppler shift' for light). Use 'Hertz effect' only if you are writing in a specific historical or highly technical physics context where the distinction is relevant and will be understood by your audience.

A phenomenon in acoustics where a sound wave appears to shift in frequency when an object moves relative to an observer, more commonly known as the Doppler effect as applied to sound.

Hertz effect is usually formal / technical / historical in register.
