• Does it lower the decibels of ambient above-surface noise, to what extent?

  • Is it preferential to filtering out low or mid or high frequencies or do they all move through it as a medium about equally in terms of perceptibillity by the submerged end observer?

    So higher is attenuated more, indeed like a low-pass filter?

    Is there a general rule or formula to calculate the reduction in volume/amplitude?
