Searching for a sound synonym can lead you in three directions, because sound works as noun, adjective and verb alike. As a noun it is what you hear (noise, tone, note, echo); as an adjective it means solid or healthy (reliable, valid, intact); as a verb it means seem.
Work out which one your sentence uses, then jump to that group. You will also find a loudness scale, phrases such as sound asleep, and the opposites for each meaning.

For volume words, the loud synonyms and quiet synonyms pages give more detail.
The soft to loud strip
The five chips climb in volume. A murmur is low voices you can barely make out. A hum is steady and low, often from a machine. Noise is the neutral middle. A racket is loud and annoying, and the word is a little informal. A din is a loud, confused mix that goes on and on, like a school cafeteria at lunch.
Clamor sits near din but adds voices, often people demanding something.
Sound advice, sound sleep, sound walls
As an adjective, sound has two main meanings. The first is sensible and well-judged: sound advice is solid, wise or reasonable advice, and a sound argument is valid, logical or well-founded. The reliable synonyms page has more for trust.
The second is in good condition: a sound roof is sturdy or intact, and a sound mind or body is healthy (see healthy synonyms). A legal phrase, of sound mind, means mentally capable.
Sound asleep means fast asleep or deeply asleep. Swap it with soundly as well: she slept soundly, or she slept deeply.
Seem, appear and come across
The verb sound means a statement or idea gives a certain impression, usually from what you hear or read. Seem is the closest general swap. Come across as is natural for people: my cousin comes across as nervous on calls. Appear is more formal and leans on what you see, so it can feel slightly off for something you heard.
- That sounds like a great plan. Swap: That seems like a great plan.
- You sound tired. Swap: You seem tired.
- It sounds strange, but it works. Swap: It may seem strange, but it works.
More options for this sense are on the appear synonyms page.
Swaps in everyday writing
A product review: "The speaker has great sound and the sound is clear even at full volume." Rewriting it as The speaker has great audio, and the tone stays clear even at full volume removes the repeat and adds a more exact word.
- A strange sound came from the attic. Try: A strange noise came from the attic.
- The plan is financially sound. Try: The plan is financially solid.
- The old barn is still structurally sound. Try: The old barn is still sturdy.
Opposites for each meaning
For the noun, use silence, quiet or hush. Hush suggests a sudden calm: the crowd went into a hush as the lights dimmed. For sensible ideas, the opposite is unsound, flawed or shaky: a shaky argument. For buildings and bodies, use damaged, weak or unsafe.

Frequently asked questions
Is noise the same thing as sound?
Not quite. Sound covers anything you hear, while noise usually means sound that is loud, unpleasant or unwanted. Music is sound; a drill outside your window is noise.
Sound advice: which adjectives replace sound there?
Solid, wise and sensible are the easiest replacements. In formal writing, well-founded and prudent also work.
When surveyors call a structure sound, what do they mean?
It is strong and undamaged. Sturdy, stable and intact are good replacements, and surveyors often say structurally sound.
Can I use seem instead of sound?
Yes, for the verb. That sounds fair and that seems fair mean nearly the same. Sound hints that you heard or read it, while seem is more general.
Is there a word for a very loud, messy sound?
Din, racket and clamor all describe loud, confused noise. Racket is the most casual, din suits writing, and clamor adds voices or protest.
What word means the absence of sound?
Silence is the standard word. Quiet and hush are softer, and stillness adds a sense of calm.
