Actually, noise is usually factored in when making distortion measurements. One should know the noise floor, and realize that beneath it, harmonics and other distortions are "invisible" to the measurement gear. They are said to be lost "below the noise floor." The term THD+N is total harmonic distortion plus noise.

Some harmonics are more discordant than others. Odd harmonics sound worse than even harmonics do, and higher harmonics sound more edgy than lower ones. So if you have 5% second harmonic in one environment and 3% fifth harmonic in another, the latter will sound worse even though the percentage of distortion in the first case is higher.
