Very quiet. Comparable to a calm office or a soft conversation.
A is a linear unit of perceived loudness. It was proposed by Stanley Smith Stevens in 1936 to provide a scale that feels more intuitive to the human brain.
Because the human ear is logarithmic (we hear in ratios, not linear steps), the conversion is exponential. For every 10 dB increase, the Sone value doubles. loudness sones
This is the most practical use of sones. Range hoods list their loudness in sones.
You are most likely to encounter sone ratings when shopping for ventilation fans, range hoods, or air purifiers. Because these devices stay on for long periods, manufacturers use sones to help consumers understand the noise impact on their environment. Very quiet
A is a unit of perceived loudness . It was created by psychoacoustician Stanley Smith Stevens to answer one simple question: How loud does this actually feel?
The sone scale offers a more intuitive measure of loudness than decibels because it directly relates to human perception. Here’s a rough guide to help you understand the sone scale: It was proposed by Stanley Smith Stevens in
| Decibels (dB) | Perceived Loudness (Sones) | Real-World Example | | :--- | :--- | :--- | | 40 dB | 1 Sone | Quiet office, bird calls | | 50 dB | 2 Sones | Light rain, moderate refrigerator | | 60 dB | 4 Sones | Normal conversation, dishwasher | | 70 dB | 8 Sones | Vacuum cleaner, busy traffic | | 80 dB | 16 Sones | Garbage disposal, alarm clock (2 feet away) | | 100 dB | 64 Sones | Pneumatic drill, loud concert |
