A device is used to monitor, in real-time, one or more environment conditions of an environment in which a user is located. Based on the monitoring, an alert condition relating to the environment is detected. Based on detecting the alert condition, on-demand testing of a sensory component of the user is initiated. The on-demand testing tests for a selected condition relating to the health of the user.

An ear-and-eye mask (10) is provided comprising a noise-attenuation-and-generation assembly (46) having a digital domain, the noise-attenuation-and-generation assembly comprising, in the digital domain, a noise cancelling-circuit (48) and a noise masking circuit (64), wherein the noise-cancelling circuit (48) receives an input from an audio capture device (56) thereof which communicates with the noise masking circuit (64). An adaptive spectral noise analyser and generator is provided which determines an unwanted remnant signal comprising the leftover unwanted frequency and/or volume after noise cancellation, and wherein the noise attenuation-and-generation assembly (46) then determines and generates a compensation frequency and/or volume for countering this unwanted remnant signal following noise attenuation for output by a speaker (36) through a stem (40) direct to the user's ears.

The present invention provides a customizable ear insert for fitting within a user's outer ear or ear canal or both and methods therefor. In accordance with an aspect of the present invention, there is provided a customizable ear insert having: a body formed of photocurable polymer, the body having a first shape configured for insertion into the outer ear canal of a user; a light source, the light source positioned adjacent the body, and wherein the body can be cured into a second shape by application of light generated by the light source, the second shape snugly conforming to the interior surface of the user's outer ear or ear canal or both.

An earplug includes a tubular member configured to extend in one direction and to be capable of bending relative to the one direction, a first acoustic sensor configured to collect sound via the tubular member, and an earplug type sound insulation member in which the tubular member is inserted. The tubular member is preferably bendable according to a shape of an external auditory meatus. A housing having a first opening being communicated with the tubular member is preferably provided. The first acoustic sensor is preferably provided in the housing and collects sound via the tubular member and the first opening.

A headset has earmuffs connected by a connection element. The earmuffs have inner sides facing each other and outer sides facing away from each other in a first transverse direction. The earmuffs extend from a bottom side to a top side in a vertical direction. The earmuffs extend from a first to a second longitudinal side in a second transverse direction. At least one of the earmuffs has a positioning pocket at the outer side with a button arranged therein. The positioning pocket extends across a width in second transverse direction that corresponds to at least 50% of a width of the at least one of the earmuffs. The positioning pocket has a bottom end and a top end and extends in vertical direction from the bottom end to the top end. The top end of the positioning pocket forms a stop edge for fingertips of an operator's hand.

A hearing device includes: at least one microphone for converting sound received by the at least one microphone into an audio signal; a sound impulse detector configured for detecting a presence of an impulse in the audio signal; and a signal processor configured for processing the audio signal into a processed audio signal in response to the presence of the impulse in the audio signal as detected by the sound impulse detector; and a receiver coupled to the signal processor for converting the processed audio signal into an output sound signal for emission towards an eardrum of a user; wherein the sound impulse detector is configured for operation in a frequency domain for detecting presence of the impulse in the audio signal.

A control unit for a worker wearing personal protective equipment is presented. The control unit includes a PPE network creator that, when activated, creates a network. The control unit also includes a PPE device identifier configured to detect a first PPE associated with the worker and a second PPE associated with the worker. The first PPE has a first speaker and a first microphone. The second PPE has a second speaker and a second microphone. The control unit also comprises a PPE network joiner that facilitates the first and second PPE joining the network. The control unit also comprises a preferred configuration selector that automatically selects a preferred speaker for the worker and a preferred microphone for the worker. The preferred speaker is the first or second speaker. The preferred microphone is the first or second microphone. The control unit also comprises a network communication component that automatically communicates a first device parameter settings to the first PPE and a second device parameter settings to the second PPE. The first and second device parameter settings are based on the selected preferred speaker and microphone.

The present application relates to a battery-powered electronic device, such as an electronic hearing protector, with switchable electrical contacts. The device includes a housing enclosing the battery and an electronics assembly. The electronics assembly is powered by the battery, and the electronics assembly comprises a processor controlled by updatable software. The device further includes a first electrical contact that is a ground line; a second electrical contact that is a data programming line in a first state, and that is a charging voltage line in a second state; and a third electrical contact that is a clock line in a first state, and that is a charge enable line in the second state.
