Your goal is to detect whether any seizure events are present in a given audio sample

Each audio sample represents 1-2 hours of multichannel EEG data intelligently compressed to few seconds of sound.

Find below a few clues on how seizures typically sound using our method and how different is the sound of background EEG.

NOTE: You would need to use headphones or speakers to listen to these sounds.

SEIZURE EXAMPLES:

1) Typical seizure events

You can easily hear a pitch-evolving sound (like a chirp) with tonal variations. Seizures evolve in time and this is perceivable by the human ear.

2) An example of a low-amplitude seizure

Seizures can be very low amplitude. It is more challenging but the pitch evolution can still be perceived.
TIP: Turn up the volume for better perception.

3) An example of a short seizure

Seizures can be very short. It can be tricky but high-pitched sounds with tonal variations are still noticeable.
TIP: You might want to listen to it twice.

BACKGROUND EXAMPLES (NO SEIZURE):

1) An example of background activity

Quiet crackling, popping or hissing sounds. No patterns, no evolution.

2) An example of an artifact

Some artifacts can mimic seizures and result in a high-pitch sound, but unlike seizures the tone remains constant, showing little or no pitch evolution.
TIP: It is just an annoying mosquito passing by...

Please choose YES when you think that the audio sample contains seizures (any)

Please choose NO when you perceive no presence of seizure events (none)

You would be reviewing a total of 79 samples of similar length. The expected duration of this survey is 10min in total. Are you ready?
