An audio apparatus for generating a flutter echo audio signal comprises a receiver () arranged to receive room metadata indicative of properties of a room. The room metadata may e.g. indicate dimensions of the room and/or acoustic reflection data for boundaries of the room. An estimator () determines a flutter echo estimate for the room in response to the room metadata where the flutter echo estimate is indicative of a level of a flutter echo in the room. A signal generator () includes a feedback delay network comprising a plurality of feedback loops. The signal generator () is arranged to generate the flutter echo audio signal from output signals of a set of feedback loops of the plurality of feedback loops being fed an audio source signal. An adapter () adapts a first parameter for a first feedback loop of the set of feedback loops in response to the flutter echo estimate.

Audio apparatus and method therefor

A sensor system comprises first and second PPG sensors. A monitoring system monitors detection by at least one of the first and second detectors an optical calibration signals, for performing time calibration between the first and second PPG sensors. This system makes use of two PPG sensors. To enable these sensors to be independent units, rather than being fully integrated into a combined system, a calibration system is provided. Based on detected optical signals, the behavior over time of each PPG sensor can be monitored and thus calibration can take place.

Sensor system and method which makes use of multiple PPG sensors

There is provided a method of operating a device to generate a target sound that is audible to a user of the device, the method comprising measuring background noise in an environment in which the device is located; using a perceptual loudness model to predict an audibility of the target sound to the user of the device based on the measured background noise; using the output of the perceptual loudness model to determine a gain value that is to be applied to a source signal used to generate the target sound in order to provide at least a desired level of audibility of the target sound to the user; applying the determined gain value to the source signal to produce a modified source signal; and generating the target sound using the modified source signal.

Apparatus and method for improving the audibility of specific sounds to a user

There is provided a system for use with a patient in a healthcare environment, the system comprising a medical device configured to monitor or treat a patient, the medical device being for use in a room in which the patient is located and comprising an alarm unit configured to issue an audible alarm; a detection unit configured to detect whether a healthcare staff member is in the room in which the patient is located; a remote alarm unit configured to issue an alarm to alert a healthcare staff member located outside the room in which the patient is located; and a control unit that is connected to the medical device, the remote detection unit and the alarm unit, the control unit being configured to: (i) control the alarm unit in the medical device to issue an audible alarm in the event that the medical device detects an alarm condition for the patient or the medical device and the detection unit detects that a healthcare staff member is in the room in which the patient is located; and (ii) control the remote alarm unit to issue an alarm to alert a healthcare staff member located outside the room in which the patient is located in the event that the medical device detects an alarm condition for the patient or the medical device and the detection unit detects that no healthcare staff member is in the room in which the patient is located.
