The word brayed, which usually refers to the harsh and loud sound made by a donkey, can be substituted with several different terms. Some possible synonyms include brattle, clamor, racket, and blare, all of which suggest a loud and perhaps unpleasant noise. Other options could include bellow, thunder, roar, or trumpet, which convey a more forceful and explosive sound. Alternatively, one might use phrases such as "let out a piercing cry" or "unleashed a deafening howl" to describe a similarly noisy event. Regardless of the specific synonym chosen, the object being described is sure to be making a sound that is both memorable and attention-grabbing.
