use-acoustics

Composable primitive acoustics utilities for Rust.

use-acoustics is the sound-specific RustUse set for small, composable acoustic calculations. It focuses on frequency, wavelength, decibels, sound pressure, sound intensity, and simple speed of sound approximations without pulling in DSP engines or heavyweight audio dependencies.

Scope

• decibels
• sound pressure level
• sound intensity level
• frequency
• period
• angular frequency
• wavelength
• speed of sound approximations

Relationship

• use-wave handles broader wave primitives.
• use-acoustics handles sound-specific primitives.
• The v0.1 API is intentionally small and mostly self-contained.

Installation

Crates.io:

[dependencies]
use-acoustics = "0.1"

Local workspace or path dependency:

[dependencies]
use-acoustics = { path = "crates/use-acoustics" }

Examples

Calculate wavelength from frequency:

use use_acoustics::prelude::*;

let wavelength = wavelength_meters(440.0, SPEED_OF_SOUND_AIR_20C_MPS).unwrap();

assert!((wavelength - 0.7795).abs() < 0.001);

Calculate SPL from pressure:

use use_acoustics::prelude::*;

let spl = sound_pressure_level_db(1.0).unwrap();

assert!((spl - 93.9794).abs() < 0.001);

Convert dB to ratios:

use use_acoustics::prelude::*;

let amplitude_ratio = db_to_amplitude_ratio(20.0).unwrap();
let power_ratio = db_to_power_ratio(10.0).unwrap();

assert!((amplitude_ratio - 10.0).abs() < 1.0e-12);
assert!((power_ratio - 10.0).abs() < 1.0e-12);
