Just as these different environmental sounds have varying loudness levels, so do individual sounds of our language.

Vowels, nasal consonants (consonants made with the vocal tract-m, n, ng), and most voiced consonants (those consonants that require the vocal folds to vibrate- such as b, d, g, z, v, j) are louder than voiceless consonants (such as f, s, th, k, sh, ch, p).
