The loudness of a bucket drum group consisting of around 20 people can vary depending on various factors, including the playing intensity, the size and material of the buckets, and the environment in which they are performing. However, it's important to note that providing an exact decibel (dB) measurement without specific information is challenging.
Generally, bucket drumming can produce a significant amount of sound, especially when performed collectively by a large group. The drums made from buckets can create a percussive and resonant sound that can carry quite far. The sound level can be influenced by factors such as the drumming technique, the presence of other instruments or background noise, and the proximity of reflective surfaces that can amplify or dampen the sound.
In an outdoor setting, where sound can disperse more easily, the overall sound level may not reach extremely high values. However, in an enclosed or acoustically reflective space, the sound produced by a group of 20 people drumming on buckets can potentially be quite powerful.
To provide a reference point, consider that a rock concert typically ranges from around 100 dB to 120 dB, which is very loud. A bucket drum group may not reach those levels, but it can still produce a substantial amount of sound, potentially in the range of 80 dB to 100 dB or higher, depending on the factors mentioned earlier.
It's worth noting that prolonged exposure to high sound levels can be harmful to hearing. If you are participating in or observing a bucket drumming performance, it's advisable to protect your ears with appropriate hearing protection, such as earplugs, especially if you anticipate being close to the group or in an acoustically reflective environment.
