Modulation Distortion in Loudspeakers
When comparing a loudspeaker with direct radiator bass system to one with horo loaded bass, the subjective judgment is that the one with the horn loaded bass is "cleaner". The difference in listening quality appears to be due to modulation distortion. The mathematical analysis of modulation distortion is reviewed and spectrum analyzer measurements are described which have been correlated with l...
متن کاملIronless Loudspeakers with Ferrofluid Seals
This paper describes the drawbacks related to the iron in the classical electrodynamic loudspeaker structure. Then it describes loudspeaker motors without any iron, which are only made of permanent magnets. They are associated to a piston like moving part which glides on ferrofluid seals. Furthermore, the coil is short and the suspension is wholly pneumatic. Several types of magnet assemblies a...
متن کاملRecording and Reproduction over Two Loudspeakers as Heard Live Part 1: Hearing, Loudspeakers and Rooms
Innate hearing processes define the realism that can be obtained from reproduced sound. An unspecified system with two loudspeakers in a room places considerable limitations upon the degree of auditory realism that can be obtained. It has been observed that loudspeakers and room must be hidden from the auditory scene that is evoked in the listener’s brain. Requirements upon the polar response a...
متن کامل3-D Audio Using Loudspeakers
3-D audio systems, which can surround a listener with sounds at arbitrary locations, are an important part of immersive interfaces. A new approach is presented for implementing 3-D audio using a pair of conventional loudspeakers. The new idea is to use the tracked position of the listener's head to optimize the acoustical presentation, and thus produce a much more realistic illusion over a larg...
متن کاملPerceiving Low Pitch through Small Loudspeakers
Since the invention of the electrodynamic loudspeakec there has been a need for greater acoustical output, especially at low frequencies. For modern-day applications it is desirable to reduce the volume of the loudspeaker (and cabinet). These two demana5 are physically contradictory. It is the aim of this paper to offer options to evoke the illusion of a higher bass response, while the power ra...
