Description: Flame Feedback is a sound sculpture constructed from a speaker driver, a candle, and electronic components. The speaker is activated with a low-frequency tone, which moves air and causes the candle to flicker. An optical sensor detects the flicker of the candle and modulates the tone based on the detected signal. Air turbulence disrupts the candle's response to the speaker in a consistent manner, resulting in the system randomly transitioning between various oscillatory modes.
The Flame Feedback sound sculpture integrates several key components that work together to create an interactive experience. The speaker driver serves as the primary actuator, generating low-frequency sound waves that propagate through the air. These sound waves induce fluctuations in air pressure, which in turn affect the candle flame, causing it to flicker in response to the sound.
The optical sensor is positioned strategically to monitor the flickering behavior of the candle flame. It detects variations in light intensity caused by the movement of the flame. This data is then processed to extract the flicker frequency, which is used to modulate the frequency of the tone produced by the speaker. This feedback loop creates a dynamic interaction between the sound and the visual element of the candle flame.
Air turbulence plays a crucial role in the overall behavior of the system. It introduces randomness into the interaction, preventing the candle from maintaining a stable flicker pattern. This instability leads to the system oscillating between different modes of operation, resulting in a unique auditory and visual experience each time it is activated.
The design of the Flame Feedback sculpture exemplifies the intersection of art and technology, utilizing principles of acoustics, optics, and fluid dynamics to create a captivating installation. The interplay between sound and light not only engages the senses but also invites contemplation on the relationship between natural elements and electronic systems.Flame Feedback is a sound sculpture built from a speaker driver, a candle, and electronics. The speaker is driven with a low frequency tone, pushing air and causing the candle to flicker. An optical sensor measures the candle flicker and frequency modulates the tone with the signal. Air turbulence prevents the candle from responding to the speaker in a consistent way, causing the system to randomly jump between different oscillatory modes.
