As an acoustics expert with a focus on sound levels and their impact on human perception, I can provide you with a detailed explanation of what 1.5 sones represent in terms of noise levels.
Sound levels are typically measured in decibels (dB), which is a logarithmic unit that expresses the ratio of a physical quantity to a reference level. However, decibels can be somewhat abstract and do not always correlate well with how humans perceive the loudness of sounds. This is where the sone unit comes into play.
The sone is a unit of loudness that attempts to quantify the perceived loudness of sound in a way that is more aligned with human perception. It is based on the idea that humans perceive sound loudness on a logarithmic scale, which means that a change from 1 sone to 2 sones sounds twice as loud, and from 2 sones to 4 sones also sounds twice as loud, and so on.
One sone is defined as the loudness of a sound that is judged by the average human listener to be as loud as a reference sound at 40 dB at 1 kHz. This reference sound is akin to the sound of a quiet refrigerator, which is a common benchmark for quietness in many environments.
When we talk about a sound being rated at 1.5 sones, it means that the sound is perceived to be 1.5 times as loud as the reference sound at 1 sone. This is a relatively quiet sound level. To put it into perspective, a quiet bathroom fan might be rated at about 1.5 sones or less, indicating that it is almost as quiet as the reference sound but slightly louder. It's important to note that the human perception of loudness can vary based on factors such as the frequency content of the sound, the environment it is in, and individual differences in hearing.
In practical terms, 1.5 sones is a level of sound that would be considered quite soft and would not be disruptive in most settings. It's a level that you might not even notice if you were not actively listening for it. For comparison, a sound at 3 sones would be perceived as twice as loud as 1.5 sones, and a sound at 6 sones would be perceived as four times as loud as 1.5 sones.
Understanding the sone scale can be helpful when selecting appliances or equipment that need to operate quietly. It provides a more intuitive measure of loudness than decibels, making it easier for consumers to make informed decisions about the noise levels of the products they choose.
In summary, 1.5 sones is a measure of sound loudness that indicates a relatively quiet sound level, slightly louder than the quiet hum of a refrigerator but still well within the range of being unobtrusive in most environments.

The lower the sone rating, the quieter the fan will be. One sone is equivalent to the sound of a quiet refrigerator, so a quiet bathroom fan will be rated at about 1.5 sones or less.
