The Application of Nanofibrous Resonant Membranes for Room Acoustics [PDF]
Nanomaterials, 2023 Solitary sound absorbing elements exist; however, their construction is massive and heavy, which largely limits their use. These elements are generally made of porous materials that serve to reduce the amplitude of the reflected sound waves.

Issues for computer modelling of room acoustics in non-concert hall settings [PDF]
, 2005 The basic principle of common room acoustics computer models is the energy-based geometrical room acoustics theory. The energy-based calculation relies on the averaging effect provided when there are many reflections from many different directions, which

Autophonic Loudness of Singers in Simulated Room Acoustic Environments [PDF]
, 2023 This paper aims to study the effect of room acoustics and phonemes on the perception of loudness of one's own voice (autophonic loudness) for a group of trained singers. For a set of five phonemes, 20 singers vocalized over several autophonic loudness ratios, while maintaining pitch constancy over extreme voice levels, within five simulated rooms ...

Room Acoustics (lecture notes) [PDF]
arXiv, 2021 Room acoustics is commonly regarded and studied as an applied subdiscipline of engineering acoustics. It is likely for this reason that many textbooks and lecture notes on the topic provide a too brief, unsystematic, and incomplete physical basics of the theory, while focusing on the practical aspects of calculation, measurement, assessment, and ...

SoundCam: A Dataset for Finding Humans Using Room Acoustics [PDF]
arXiv, 2023 A room's acoustic properties are a product of the room's geometry, the objects within the room, and their specific positions. A room's acoustic properties can be characterized by its impulse response (RIR) between a source and listener location, or roughly inferred from recordings of natural signals present in the room.

Efficient Synthesis of Room Acoustics via Scattering Delay Networks [PDF]
, 2015 An acoustic reverberator consisting of a network of delay lines connected via scattering junctions is proposed. All parameters of the reverberator are derived from physical properties of the enclosure it simulates. It allows for simulation of unequal and

Adaptive inverse filtering of room acoustics [PDF]
, 2008 Equalization techniques for high order, multichannel, FIR systems are important for dereverberation of speech observed in reverberation using multiple microphones. In this case the multichannel system represents the room impulse responses (RIRs).

An Evaluation of Room Acoustics in Rooms Used for Turkish Melodic Music
Megaron, 2015 Developing since the early 1920s, the discipline of room acoustics has made important strides in correlating subjective and objective, or measurable, values for music rooms.

Cognitive load associated with speaking clearly in reverberant rooms [PDF]
Scientific ReportsCommunication is a fundamental aspect of human interaction, yet many individuals must speak in less-than-ideal acoustic environments daily. Adapting their speech to ensure intelligibility in these varied settings can impose a significant cognitive burden.

MOSRA: Joint Mean Opinion Score and Room Acoustics Speech Quality Assessment [PDF]
arXiv, 2022 The acoustic environment can degrade speech quality during communication (e.g., video call, remote presentation, outside voice recording), and its impact is often unknown. Objective metrics for speech quality have proven challenging to develop given the multi-dimensionality of factors that affect speech quality and the difficulty of collecting labeled ...
