Our Bluetooth speaker has the ability to change the dB level by an firmware update done in house, at the time of order placement only. (This is not the same chipset used for changing the name and pin number)
Hotels have 3 levels of category rating
Category 1 rooms are the quietest, allowing noise levels of up to 43 decibels.
Category 2 rooms allowing noise levels of up to 48 decibels
Category 3 rooms allowing noise levels of up to 54 decibels
A typical conversation is 60dB as a guide
Our speaker has a volume limiter as standard which reduces volume dB from peak 120dB to approx 80dB as standard. (This can vary according to music played)
