“The Cumaean Sibyl cave is a mythological place in the north of Naples, where the Sibyl, a priestess presiding over the Apollonian oracle, received the travellers and predicted their future. The cave is length about 140 m, with trapezoidal section excavated in the rock of tuff. The cave has a height of about 4.5 m and it is 2.4 m wide. The legend says that the Sibyl received the travellers in the final part of the cave. Acoustic measurements were done with an omnidirectional sound source in the in the room inside the Sybil cave while positioning the microphones along the cave.”

Hidden away and mysterious, with beautiful reverb.  We positioned the microphone marked with a red dot in the chamber past the Second Chamber.  As you can see on the survey, the cave continues much deeper.  After this ‘third’ chamber, the tunnel gets very narrow and tricky to move with equipment. In this schematic the microphone (M1) is indicated in red and source positions (S-2 - S7) indicated in green.

Ionion Mirror (part 1): This location in the sea was a tragic site where refugees drowned. A performance video/sound piece was created from this exact point in the water with sounds and video from above and under water (Cobi van Tonder). The acoustics are currently presented as an impression rather than via the standard impulse response methods of taking acoustic measurements. Sing into this space to hear the resonances from the drone music. A short distance from this point is a tiny little island called Zeus, seen in the reflection of the mirror.

Melissani Cave is located on the island of Kefalonia, in the Ionian Sea. In Greek mythology, Melissani was the Cave of the Nymphs. It features a lake surrounded with trees and forest, and is located east of the mountains of Evmorfia and Agia Dynati. The Ionion Art Centre, Kefalonia is making work here possible.

The Cathedral Church of St Peter and St Wilfrid, known as Ripon Cathedral, and until 1836 known as Ripon Minster, is a cathedral in the North Yorkshire city of Ripon. Founded as a monastery by Scottish monks in the 660s, it was refounded as a Benedictine monastery by St Wilfrid in 672. The present church is the fourth, and was built between the 13th and 16th centuries. The cathedral is notable architecturally for its gothic west front in the Early English style, as well as the Geometric east window.

Set in a bay at the foot of high chalk cliffs this sand and pebble beach stretches for around 1.2km. Many rockpools, at low tide and hardly any beach at high tide.  Sea lions, gannets, oyster-catchers, gulls and eider ducks can all be found here. There has been a lighthouse near this spot since the 17th century.  The current structure, built in 1806, still guides vessels safely around the rocky headland.

The Tvísöngur Sound Sculpture designed by German artist Lukas Kuhne is situated in the mountains above Seydisfjordur, northeast Iceland. This mushroom-looking concrete sculpture consists of interconnected domes in different sizes. Each one of the domes has a resonance that corresponds to a tone in the Icelandic musical tradition of five-tone harmony and it serves as Helmholtz resonators, as the wind blowing in off the cliffs rushes into and across the openings, the air within the structure resonates.

“According to the legend, witches were women with magical knowledge that with the use of herbs cured illnesses and performed spells. In 1639, the book “De Nuce Maga Beneventana” described how the place where the “witches” gathered was an area south of the city of Benevento in South Italy in a long and narrow gorge. This valley with high rock walls was called the “stretto di Barba”. According to the legend, under a walnut tree in the “stretto di Barba”, the Longobards were used to perform sacred rituals. To make the rituals more effective, the sounds were amplified by the narrow gorge with flat and parallel rock walls”. Researched and recorded by Gino Iannace, Umberto Berardi, and Amelia Trematerra. (URL: [researchgate.net/publication/328378258_The_acoustics_of_the_Witches_Valley](http://researchgate.net/publication/328378258_The_acoustics_of_the_Witches_Valley))

“Acoustic measurements were carried out using an impulsive sound source located in the valley. The height of the sound source and microphones were maintained fixed at 1.6 m from the floor. A digital four channels microphone was used, which also allowed converting the recordings into an Ambisonics B-format. The microphone BRAHMA is composed of four microphones arranged in a tetrahedral array and allows to convert the original format into an orthogonal sound recording during the post-processing. The microphone was located along the radial direction at a constant pitch. The recorded impulse responses were then elaborated with the software Dirac 4.0, and the several acoustic parameters defined in the ISO 3382-1 \[14\], such as the reverberation time (T30), early decay time (EDT), the definition (D50), and the sound transmission index for speech intelligibility (STI) were analysed.”

York Cathedral was built between the 12th and 15th centuries on the foundations of the previous Norman church that was in turn constructed on the foundations of the original Roman fortress.

Its dimensions are approximately 27m high to the vaulted ceiling, 160m long and 76m wide. 

It is constructed mostly of stone with extensive, large panels of stained glass windows.
