Can you tell me what the sound decibels are at 15 feet?

Hello, thanks for your question. With these Modine models disruption isn’t a concern, they are designed for quiet operation. At a distance of five feet, Hot Dawg HD decibel levels range from 53 dB to 58 dB. For comparison, normal human speaking volume at a distance of three feet is between 60 dB and 65 dB. Even the largest Hot Dawg HD model is quieter than a conversation.
