A record "longest echo" within the Inchindown oil despository

Area of Science:

• Acoustics
• Environmental Science

Background:

• Guinness World Records recognized tank number 1 at the Inchindown oil depository, Scotland, for the "longest echo" in 2013.
• The measured phenomenon is technically reverberation, not an echo.
• The tank's acoustic properties are unique and warrant documentation.

Purpose of the Study:

• To document the unique acoustic space of the Inchindown oil tank.
• To detail the methodology used for measuring reverberation time.
• To discuss the factors contributing to the tank's exceptional reverberance.

Main Methods:

• Acoustic measurements were taken within tank number 1 at the Inchindown oil depository.
• Reverberation time was specifically measured at 125 Hz.
• Methodology for record-breaking attempts is detailed.

Main Results:

• The reverberation time in the Inchindown oil tank was measured to be 112 seconds at 125 Hz.
• This significantly exceeds the previously recognized "longest echo" record of 75 seconds.

Conclusions:

• The Inchindown oil tank is a unique acoustic environment with an exceptionally long reverberation time.
• The study provides valuable data for acousticians and record-seekers interested in this phenomenon.
• Further research into the specific acoustic characteristics of the tank is suggested.
