Hi, my name is Guillermo, I'm an electronic engineer and writer of ebooks. More details about my project, and the experiments that I plan to perform are shown below:
What problem I'm going to solve?
There're some concerns that ground-borne perceptible vibrations and both ground-borne and airborne sound transmission from nearby rail and vehicle traffic could pose a potential risk to the well being of many different aquatic species to be housed in the aquaculture tanks; in particular acoustically sensitive sharks, turtles and “bony fish”.
What I'm going to build to solve this problem?
As a precaution, I'm going to undertake a study that includes investigating and identifying the threshold sound or vibration levels that might adversely affect these aquatic species in terms of their health, behaviour and reproductive capabilities.

How does my solution work? What are the main features?
Noise levels in the water within aquarium tanks are generated by the movement of the boundary. As tanks are supported from the ground, ground-borne vibration will cause corresponding motion of the water at the bottom of the tank. Resulting sound pressure levels in the water depend on various factors, such as the size of the tank and the depth of the water.
The hearing range of bony fishes varies greatly with species. Ambient noise levels in the ocean generally peak at around 100 dB at lower frequencies, which is near the frequency at which the vibration levels from the trains and vehicles would be produced.
Including my own aquarium, also I'm going to visit some yet undeveloped site and conduct measurements of the ground-borne vibration and outdoor sound levels. Vibrations from various vehicles will be measured, including passenger and freight trains that pass through the main corridor.
Experiments that I plan to perform:
- I'm going to program the "X-NUCLEO-IDB05A1" and "NUCLEO-H743ZI" boards by means of the STM32Cube MCU software.
- I will also use the Android application "ST BlueNRG" to connect to the bluetooth BLE system and monitor the vibration sensor.
- Measure Noise and Vibration Impact on Sea-life Health and Well-being
- Meassure Noise and Vibration Impact on Sea-life Behaviour
- Meassure Noise and Vibration Impact on Sea-life Reproduction
