Booming describes something growing rapidly or making a deep, loud, resonant sound.

When a business is booming, customers flood in and sales skyrocket. A booming economy means jobs are plentiful and companies are expanding. A town experiencing a population boom grows so fast that new schools and houses spring up everywhere. The word captures explosive, energetic growth that happens powerfully and noticeably.

The word also describes deep, loud sounds that echo and resonate. Thunder booms across the sky. A bass drum makes a booming sound that you can feel in your chest. When someone speaks in a booming voice, their words carry across a crowded room without any microphone. This kind of boom is powerful and impossible to ignore, like a cannon firing or fireworks exploding overhead.

Both meanings share that sense of force and impact. Whether it's a booming tech industry or a booming announcement echoing through a canyon, something booming demands attention because of its sheer power and presence.
