Components of Aural Architecture

How to process Urban noise

How to process ?

Flow of  Water and birds chirp  has the capacity to curb Urban noise around us in the metropolitan cities . Flow of water and noise has the same frequency so when overlapped it  has the power to nullify the effect through the concept of Standing wave .As architects we do not consider the Aural experience of a space ,by increasing the greenery and flow of water as urban elements ,the experience is enhanced.

Technique behind epidaurus

Acoustic traps

The corrugations on the surface of the seats act as natural acoustic traps. Though this effect would seem to also remove the low frequencies from the actors' voices, listeners actually fill in the missing portion of the audio spectrum through a phenomenon known as virtual pitch. The human brain reconstructs the missing frequencies, producing the virtual pitch phenomenon, as in listening to someone speaking on a telephone with no low end.

The findings are detailed in the April issue of the Journal of the Acoustics Society of America.

Amazingly, the Greek builders of the theater did not themselves understand the principles that led to the exceptional audibility of sound from the stage.

Attempts to recreate the Epidaurus design never quite matched the original. Later seating arrangements featured other materials, such as wood for the benches, an approach which may have ultimately derailed the design duplication effort.

Ancient temples Secret revealed !!

Why 110 Hz?

Many archaeo-acoustic investigations of prehistoric, megalithic structures have identified acoustic resonances at frequencies of 95-120 Hz, particularly near 110-12 Hz, all representing pitches in the human vocal range. These chambers may have served as centers for social or spiritual events, and the resonances of the chamber cavities might have been intended to support human ritual chanting.

Findings are compatible with relative deactivation of language centers and a shift in prefrontal activity that may be related to emotional processing. These intriguing pilot findings suggest that the acoustic properties of ancient structures may influence human brain function, and suggest that chanting might have been used to enhance right brain activities.
