Ever since the invention of the electrodynamic loudspeaker there has been a need for greater acoustical output, especially at low frequencies. From a manufacturer’s point of view it has been desirable for a long time to reduce the size of the loudspeaker (and cabinet). These two demands are physically contradictory. Options are being offered to evoke the illusion of a higher low-frequency response of the loudspeaker while the power radiated by the loudspeaker at those low frequencies remains… Expand
Improving percieved bass and reconstruction of high frequencies for band limited signals
Bandwidth extenstion methods are required in systems that playback bandlimited signals (e.g. telephone, MP3) or that are not capable of reproducing signals with a large bandwidth (small orExpand
Loudspeaker Frequency Response Measurements and Bass Reproduction
TLDR
Ways to solve the low-frequency reproduction problem of smaU-, and mediwn-sized loudspeakers by means of psychoacoustic bass processing are proposed as discussions at the end of this paper. Expand

Part 1 : Two-to-Five Channel Sound Processing 1
Today and tomorrow's audio and video, portable audio and multi-media applications put increasing demands on sound reproduction techniques. On one hand there is a need for reductions in both cost andExpand
Applications of DSP for sound reproduction improvement
TLDR
Various examples will be given, such as increasing the perceived bass response of loudspeakers, and increasing the number of loudspeaker channels (converting stereo to multichannel sound), and the same percept can be simulated over headphones. Expand

A new method is presented for the design and evaluation of loudspeaker crossover filters. The desired system characteristic can be prescribed by a (complex) acoustic transfer function rather than anExpand
Some parameters influencing the perceptibility of pitch.
TLDR
For white noise with its attenuated repetition and for sequences of pulse pairs with each second pulse attenuated, the threshold of perceptibility of pitch has been determined as a function of the pulse‐pair interval T, the sensation level SL, the bandpass center frequency f0, and the delay time τ.
