What is the best way to capture two high-frequency queries for a promoted niche on one page?

Question

Search Engine Optimization

Example:
1. Voices of "hedgehogs" (conditionally);
2. Sounds of "hedgehogs" (also conditionally).
In h1 put 1 option.
The page contains SEO text both about sounds and about voices (there are no headings other than h1 on the page).
Result:
1st place in 1 option;
3rd place in 2 options.
Question: is it possible to cover both high frequencies in h1 by writing, for example, conditionally - voices and sounds of "hedgehogs" ?
PS We consider only synonyms, if the HF are radically different, we do not consider them.

Answer 1

Theoretically, everything is possible. In practice, you need to look at clustering by TOP and competitors.
And from experience it is better to adhere to the rule "do not touch what works." Any changes can work in a negative direction.
