Loudness measurement with spectral modifications
TLDR
In this article, the perceived loudness of an audio signal is measured by modifying a spectral representation of the audio signal as a function of a reference spectral shape so that the spectral representation conforms more closely to the reference signal spectral shape.Abstract:
The perceived loudness of an audio signal is measured by modifying a spectral representation of an audio signal as a function of a reference spectral shape so that the spectral representation of the audio signal conforms more closely to the reference spectral shape, and determining the perceived loudness of the modified spectral representation of the audio signal.read more

Patent
Audio gain control using specific-loudness-based auditory event detection
TL;DR: In this paper, a dynamic gain modification is applied to an audio signal at least partly in response to auditory events and/or the degree of change in signal characteristics associated with said auditory event boundaries.
Patent
System for adjusting perceived loudness of audio signals
TL;DR: In this paper, a method of adjusting a loudness of an audio signal may include receiving an electronic audio signal and using one or more processors to process at least one channel of the audio signal to determine the loudness.
Patent
System for increasing perceived loudness of speakers
TL;DR: In this article, a system can be provided for increasing loudness of an audio signal to present a perceived loudness to a listener that is greater than a loudness provided natively by a loudspeaker.
Patent
Loudness Modification of Multichannel Audio Signals
TL;DR: In this paper, the perceived loudness of each individual channel may be scaled by changing the gain of the individual individual channel, wherein gain is a scaling of a channel's power.

Audio signal loudness measurement and modification in the MDCT domain
TL;DR: In this article, the authors proposed a smoothing time constant commensurate with the integration time of human loudness perception or slower to measure the loudness of a time-sampled real signal.

Calculating and adjusting the perceived loudness and/or the perceived spectral balance of an audio signal
TL;DR: In this paper, the authors proposed a measurement and control of perceived sound loudness and the perceived spectral balance of an audio signal, which is useful in one or more of: loudness-compensating volume control, automatic gain control, dynamic range control (including, for example, limiters, compressors, expanders, etc.), dynamic equalization, and compensating for background noise interference in an audio playback environment.
Patent
Method, apparatus and computer program for calculating and adjusting the perceived loudness of an audio signal
TL;DR: One or a combination of two specific loudness model functions selected from a group of two or more of such functions are employed in calculating the perceptual loudness of an audio signal as mentioned in this paper, which results in a perceived loudness substantially the same as a reference loudness.

TL;DR: In this article, an indication of the loudness of an audio signal containing speech and other types of audio material is obtained by classifying segments of audio information as either speech or non-speech.
Patent
Method and apparatus for determining acoustic parameters of an auditory prosthesis using software model
TL;DR: In this paper, a software model of the auditory characteristics of an auditory prosthesis is stored independently of the actual audio prosthesis being fitted to determine the acoustic parameters to be utilized.

Method for automatic amplification adjustment in a hearing aid device, as well as a hearing aid device
TL;DR: In this paper, during the operation of the hearing aid device, speech signal levels and noise signal levels are determined in a plurality of frequency bands of an input signal, and an automatic adjustment of the amplification follows, dependent on the determined signal level and the signal frequency.
