What adjective describes a sound that is high-pitched and piercing?

The adjective that describes a sound that is high-pitched and piercing is shrill. This word specifically refers to a sound that is sharp and penetrating, often associated with a high frequency that can be uncomfortable to hear. It conveys an immediate sensory reaction, often bringing to mind an image of a loud, acute noise, such as a whistle, a siren, or a distressed animal's call. The other adjectives do not relate to sound: squalid pertains to something dirty or miserable, servile describes a submissive or obsequious attitude, and sculpted refers to the shaping or forming of something, typically in a three-dimensional context. Thus, shrill is the term that best captures the essence of a sound that is both high-pitched and piercing.
