Geoffrey Glen Martin

Title: Geoffrey Glen Martin: Innovator in Sound Technology

Introduction

Geoffrey Glen Martin is a notable inventor based in Vinderup, Denmark. He has made significant contributions to the field of sound technology, holding a total of 3 patents. His work focuses on enhancing sound reproduction and spatial audio experiences.

Latest Patents

One of his latest patents is for "Loudspeaker position estimation." This invention automates the estimation of the position of a set of loudspeakers in a room. By measuring impulse responses, the distances between each pair of loudspeakers are estimated, forming a distance matrix. This matrix is then utilized by a multidimensional scaling (MDS) algorithm to estimate the coordinates of each loudspeaker. An improved coordinate estimation can be derived by utilizing the stress values provided by the MDS algorithm.

Another significant patent is for the "Recording, synthesis and reproduction of sound fields in an enclosure." This invention simulates sound fields in enclosures, which is particularly useful for listening tests. The system includes a binaural synthesis portion that synthesizes sound based on measured impulse responses stored in a database. It also features a binaural recording portion that stores binaural recordings of other sound signals made in the room. The data from these databases are mixed and reproduced through headphones equipped with a head tracker to account for the listener's head movements. The invention employs cross-fading functions to enable dynamic listening conditions during the simulation process.
