      Another quality that bothers me is Brendel's inconsistent sonority. The treble is hard and pingy; the midrange is weighed down with a booming bass.
  2. (linguistics, phonetics) Relative loudness (of a speech sound); degree of being sonorous.
    • 2009, Ulrike Gut, Introduction to English Phonetics and Phonology, Bern: Peter Lang, →ISBN, page 81:
