Starting from the spatial distribution of the reflectors, their acoustic properties, and the location and the radiation characteristics of sources and receivers (listening points), geometric methods cast rays in space and track their propagation and interaction with obstacles in the environment [4].
'Listening points' were also established in near the mining sites, providing children working in and near the mines with counselling services and safe places to play.
UNICEF partner Programme d'Appui à la Lutte Contre la Misère (PAMI) has set up listening points in five locations in an effort to register unaccompanied minors and reunify them with their families.
For the next hour, we drove through neighborhoods, trying to find additional listening points that could help narrow down the whereabouts of the lion family.

The total sound pressure and particle velocity at the listening point (center of listener's head) generated by multiple loudspeakers are approximatively equivalent to those by the single sound (or loudspeaker) at the location of virtual sound.
Mr. Huebert described this polar station, bristling with antennas and far from urban radio pollution, as "a very clear listening point, like going to the top of a hill".
These subjective indices showed correspondence with the source to listening point cross-correlation.
r is the distance from the loudspeaker to the listening point, and in the spherical 22.2 multichannel, all loudspeakers have the same distance.
The main application scenario of the proposed method is medium and high bitrate, and the sound pressure at the center listening point is the most important in multichannel audio and the VBAP panning method.
For a multiway loudspeaker system, such as that one shown in Figure 1, we introduce the following notations: (i) : transfer function of the transducer measured at a listening point, one meter away from the top transducer (generally reproducing the high frequencies: tweeter); (ii) : transfer function of the crossover filter applied to the transducer.
When transducers have a separate geometrical distribution, the crossover design is generally done for a particular on-axis listening point, by including extra delays to correct the differences between the propagation time of the sound waves coming from all the transducers [1, 4].

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
