noisy
嗷 centers on loud, clamorous noise, often from a crowd or a chaotic scene.
嗷 combines 口 (mouth) with 敖, which likely contributes the sound and suggests loudness or clamor. The exact historical development of 敖 is uncertain.
A mouth 口 beside 敖, a shape associated with pride or loudness, suggests a noisy, clamorous scene.
For ゴウ, imagine a noisy crowd going wild: going -> ゴウ, and the mouth 口 amplifies the roar.
