However, depending on the context, you could use:
* Clearly: This emphasizes the ease of hearing something. Example: "The music was clearly audible from the street."
* Distinctly: This suggests that the sound is easily identifiable and separate from other sounds. Example: "He could distinctly hear the ticking of the clock."
* Loudly: This emphasizes the volume of the sound, which is implied by "audible" but not directly stated. Example: "The crowd cheered loudly, their voices audible even from blocks away."
* Distinctively: This implies a unique or recognizable sound. Example: "The car's engine had a distinctively audible cough."
You could also use adverbs related to the location of the sound, such as "nearby," "closely," or "far away."
Ultimately, the best adverb to use will depend on the specific meaning you want to convey.
