optimum conditions, especially at night in a quiet room.
Every air pump generates vibration and buzzing noises, which may be audible to a certain degree. These can be minimised
noticeably by counter-pressure. Reduction of the flow rate e.g. by a hose clamp or an air tap reduces the noise level
significantly.
Therefore, NEVER operate the air pump "idle", i.e. without a connected hose with an air stone or similar! This results in
premature wear of the diaphragm and an increased noise level.
