We have reached 10,000 participants in our experimental program.
Thank you all for your cooperation and support.

Now, regarding this latest tentacle sound, it might be a bit more intense than previous ones—what do you think?
To celebrate reaching 10,000 participants, we pushed a little and managed to get approval from AIFRA, allowing us to release it to everyone. Considering the experiments, it will still be necessary to conduct comparative tests with lower-intensity responsive acoustics, so it may be difficult to maintain this level all the time. However, we hope to occasionally provide more challenging responsive acoustics as well.

We appreciate your continued participation and support in our experiments.

Our research institute studies “responsive acoustics” emitted by organisms inhabiting the Abyss, a realm beyond terrestrial human perception.

These organisms use responsive acoustics for communication, territory marking, courtship, and even hypnotizing or weakening prey.
These sounds go beyond normal auditory signals, directly affecting the listener’s nervous system and altering mental states.

We predict these acoustics also affect terrestrial humans and collect experimental data through this YouTube channel.
So far, they have been observed to trigger responses similar to Autonomous Sensory Meridian Response (ASMR) in humans, but their full psychological impact is unknown.
We invite willing participants to watch the videos.

Please note that, although we record these acoustics in a proprietary format, uploading to YouTube requires conversion to standard formats, which may cause loss, distortion, or noise.
Thank you for your understanding.
