[Eeglablist] Physical vibrations affecting EEG results?

[Pål Gunnar Larsson]

Hi

I don’t think vibration affect the equipment until it starts falling apart. However, it affects patients and may influence recordings through changes in arousal (e.g. sleep recording) and attention (e.g. cognitive tests).

Hi,

Does anyone know the threshold limit for physical tremors/vibrations affecting EEG readings?

We are relocating the EEG lab to another room which is on the third floor of a building next to busy main road. When heavy trucks go past you can feel a physical tremor in the buildings floor and walls.

To this end, we are hiring some equipment to measure the vibrations (commonly measured in Peak Particle Velocity (PPV), Displacement and Acceleration) but we need to know what the limits are. Please can someone advise us on this?

Kindest Regards,
David Brookes
