"The level and distribution of underwater noise is growing at a global scale but receives very little attention, " says Dr Slabbekoorn.

Conventional CMOS image sensors mount the pixel section and analog logic circuit on top of the same chip, which require numerous constraints when wishing to mount the large-scale circuits such as measures to counter the circuit scale and chip size, measures to suppress noise caused by the layout of the pixel and circuit sections, and optimizing the characteristics of pixels and circuit transistors.

This makes it easier to scale up the number of disks in the drive while keeping drive power consumption and acoustic noise at acceptable levels (and even lower than the air filled drives).

"Noise pollution is so ubiquitous that it may be a factor in some large-scale declines in biodiversity, " says Dr Barber.
