Listening Room
|
The Listening Room of the Engineering Department of the University of Ferrara is a laboratory designed and implemented to playback a 3D acoustic field, measured o virtual. The system, constituted by 8 speakers, allows to re-create in laboratory a listening sound experience analogous to the one experienced in a real environment, preserving the spatial characteristics of the sound field. |

|
The room has a volume of 60 m3, all the boundaries (walls, floor and ceiling) are lined with 12 cm thick polyester fibre panels with a density of 40 kg/m3, guaranteeing a reverberation time lower than a 0.1 s above 300 Hz. The background noise measured inside the room (Leq) is lower than 20 dB(A). Eight Tannoy 6D Precision speakers and a subwoofer are installed inside the listening room. A multichannel probe and a VR viewer allows to create immersive multisensory virtual environments. The listening room is equipped with a specifically developed software for psycoacoustic testing, named Intelligo. The software manages the development, the auditory presentation of the stimuli, the data collection and analysis of individual or multiple-participants (up to 25 listeners) tests. |

Performed tests
The listening room is mainly employed for the evaluation of the effects of the sound field on human perception, by means of listening tests. In particular, activities are carried out regarding the acoustic design of indoor evironments (geometrical analysis, material investigation, effects of background noise) and the industrial needs (acoustic design, sound quality assessment, ect…).
