Case No. #1069
Madagascar Highlands, Anomaly of Acoustic Null Zone
Summary
Since November 2019, an anomalous phenomenon involving complete acoustic disappearance within a specific airspace has been reported in the remote Anjanaharibe-Sud Special Reserve in the Madagascar Highlands. A silent, pitch-black, cuboid object observed approximately 300 meters overhead is associated with this effect. Directly beneath it, within an estimated 50-meter diameter, all sound is completely suppressed. The acoustic null zone moves in tandem with the object's movements. Authorities have yet to identify the cause, classifying it as a spatial anomaly unexplainable by known physical laws.
Details
On November 3, 2019, at 14:30, a team of biologists conducting observations in the remote Anjanaharibe-Sud Special Reserve in the Madagascar Highlands discovered a silent, pitch-black, cuboid object hovering approximately 300 meters above them. Immediately after its appearance, all sounds—bird calls, wind noise, and even team members' voices—completely vanished from the space directly beneath it. The area was enveloped in an uncanny silence, as if in a vacuum.
Elders of the local Sakalava tribe connect this phenomenon to an ancient legend of the 'Black Stone in the Sky,' stating, 'When it appears, the forest falls silent.' In recent years, multiple similar sightings have been reported by NGO environmental researchers and rare explorers. The November 3, 2019, report from the biologist team was particularly valuable, as their high-sensitivity microphones for low-frequency observation provided precise data on the timing and extent of the acoustic nullification.
Authorities launched a discreet investigation into the incident on February 15, 2020. The team deployed high-sensitivity acoustic sensors, laser rangefinders, and small UAVs to understand the phenomenon. The object was found to be a near-perfect cuboid with a completely non-reflective, pitch-black surface. The acoustic null zone directly beneath it spanned an estimated 50-meter spherical area, where all frequency bands of sound were completely unrecorded.
However, the investigation proved challenging. Each attempt by UAVs to approach the object resulted in critical malfunctions of their control systems. Furthermore, their high-resolution cameras and acoustic recording devices repeatedly experienced inexplicable freezes. Recovered data showed a complete absence of acoustic data within the null zone, including even normal noise components, indicating an extreme recording anomaly unexplainable by typical electromagnetic interference. Consequently, direct conclusive evidence of the phenomenon remained elusive.
The object exhibits no discernible pattern of appearance, hovering for several hours to several days before silently vanishing without warning. After its disappearance, the acoustic environment instantaneously returns to normal. Repeated investigations by authorities have failed to identify any regularity or recurrence conditions for this peculiar phenomenon. While infrequent, its scope of influence is undeniable. Local testimonies remain consistent, affirming the phenomenon's existence.
This incident defies explanation by known physical laws. It suggests either direct interference with space itself or acoustic shielding by an unknown energy field. The agency classifies this phenomenon as a top-priority monitoring target, strengthening cooperation with the Malagasy government, and continues ongoing observation and data collection.

Witness Testimony
Biologist A'That silence was unnatural. I couldn't hear the wind, not even my own breath. The object overhead was like a hole ripped in space. Our instruments fell completely silent.'
Local Resident B'The black stone in the sky has always been here. When it appears, the forest becomes quiet. Nothing can be heard. My grandfather told me it's a sign of bad things to come.'
Kyuu's Analysis
An inexplicable spatial anomaly. Is the acoustic nullification due to interference? Continuous observation is imperative.
