About as loud as a shop vac
About a vacuum cleaner at 1 meter distance.
A sound level of 70 dBA is considered moderately loud. It is comparable to the sound of a vacuum cleaner or heavy traffic from a distance. Prolonged exposure to sounds at this level may lead to potential hearing damage, especially in occupational settings without proper hearing protection. Generally, 70 dBA is noticeable and can be disruptive in quiet environments.
dBA stands for A-weighted decibels, a unit used to measure the loudness of sound. It adjusts the measurement to account for the sensitivity of the human ear to different frequencies, providing a more accurate representation of how loud a sound is perceived by humans.

A noise level of 57 dBA is considered moderate in loudness. It is comparable to the sound of a quiet office, a normal conversation, or background music. While not disruptive, it can be noticeable in quiet environments. Prolonged exposure to this level may be uncomfortable for some individuals, but it typically does not pose a significant risk to hearing.
51dba is almost 3 times quieter than 59 dba.
About the same as a normal conversation between two people standing three feet apart.
