Introduction to TV Sound Engineering to post-production film sound. As television sound equipment grows more complex, those in the field must continuously learn in order to survive. If you can master the technology, you can master the art of sound. Dynamic dimensional soundscapes are possible for the creative sound Size: 4MB. Virtual home theater (VHT) is a commercial 3-D sound technology that allows playback of 4- or channel material through two loudspeakers. There are currently no standards that describe how these systems should be evaluated. A scientific method for subjectively evaluating VHT systems is described that controls the problematic nuisance variables that are unique to 3-D audio reproduction.

A study was done to subjectively compare and rank the sound field characteristics of a vehicle equipped with a 'high end' home surround sound processor and to assess compatibility of several discrete and matrix decoding modes in combination with both discrete and down mixed source materials. A vehicle was fitted with a 3/4-loudspeaker arrangement () and evaluated with optimized amplitude. NHK is planning 8K Super Hi-Vision (SHV) broadcasting with multichannel sound as a new broadcasting service. The current loudness measurement algorithm, however, are only standardized up to channels in Recommendation ITU-R BS To extend the algorithm beyond ch, we conducted a subjective loudness evaluation of various program materials and formats.

"The book provides a fascinating and incredibly informative introduction to the world of film and television sound and is well recommended."--James Eade, Lighting and Sound International "Holman covers a lot of ground in just over pages. His knowledge of the subject and many of the major industry players is by: Abstract. Stereophonic sound, or stereo as it is usually called, refers to any system of recording or sound transmission using multiple microphones and loudspeakers. Signals picked up by the microphones are routed to loudspeakers that are placed in a geometrical array corresponding to the microphone : John Eargle.

A series of subjective tests has been conducted to assess the improvement given by stereophonic sound with television in comparison to the conventional monophonic equivalent. The test material. A series of subjective tests were conducted to assess the improvement given by stereophonic sound with television in comparison to the conventional monophonic equivalent.

The test material consisted of extracts from eight, recently produced, television stereo programs. viewer. is the recommended angle for stereo listening and indeed, this is the preferred con- figuration in television production areas.

However, it was appreciated that some viewers, for reasons of convenience or the nature of television stereo, may prefer a narrower angle and this is discussed later in Section 4.

audio recorders were evaluated in a double-blind A-B comparison listening test. The majority of stereophonic popular music is produced for loudspeaker reproduction [1].

But in recent years, more and more consumers are using headphones [2], and so a concern has been raised. This paper presents a formal evaluation of the perceived sound quality provided by several spatial audio formats accompanied with video in the context of television broadcasting.

CONCLUSION Subjective evaluation of the addition of two height channels to ITU-R multichannel stereophonic reproduction was conducted. Listener ratings of the overall-impression of rendered sound fields (denoted by appropriateness) were modulated by the loudspeaker position, but were not modulated by the rendering method (IR height).

Subjective evaluation of phantom acoustic scenes. Several documents of the European Broadcasting Union, EBU, deal with the evaluation of program material in production and broadcasting.

In particular, 2-channel material for loudspeaker reproduction, which is rendered as a phantom acoustic scene, is assessed by six parameters: Spatial impression; Stereo impression; Transparency; Sound balance.
