Having a loud, deep sound or a booming quality; this form indicates a greater degree of that quality.

The word 'boomier' is derived from 'boom' (originating from the Dutch word 'boom', meaning tree or a sudden increase) and the suffix '-ier' (meaning more). The term 'boomier' refers to something that is more booming or experiencing a greater increase or growth.
Think of 'boom' as a sudden increase or growth, and remember that 'boomier' means experiencing even more of that growth.
