A tsunami detection buoy is one of the primary instruments used to detect tsunamis. These buoys are equipped with sensors that can detect changes in water pressure caused by a tsunami wave passing overhead. The data collected by these buoys is then transmitted to monitoring stations to provide early warnings.

A sound level meter is typically used to detect noise. It measures the intensity (loudness) of sound in decibels (dB) to quantify noise levels in different environments.
An electrocardiogram (ECG or EKG) is the instrument used to detect electrical currents from the heart. This test records the electrical activity of the heart over a period of time, typically a few minutes, to assess its health and function.
