A sound spectrogram measures the frequency and wavelengths of sound waves. The frequency is measured in Hertz and the wavelengths are measured in meters.
Distance-wavelength lambda (λ) is measured in meters (m)Time- frequency is measured in Hertz (Hz)

Sound is measured in decibels

Sound is measured in decibels and is symbolized dB
sound is measured in decibles
Sound is measured in decibels, which are commonly shortened to "dBs".
There is really no standard distance from the sound source where the sound pressure level (SPL) is measured.
