The present subject matter relates generally to hearing assistance devices, and in particular to a gateway for a wireless hearing assistance device.
Modern hearing assistance devices, such as hearing aids, typically include digital electronics to enhance the wearer's listening experience. Hearing aids are electronic instruments worn in or around the ear that compensate for hearing losses by specially amplifying sound. Hearing aids use transducer and electro-mechanical components which are connected via wires to the hearing aid circuitry.
Hearing assistance devices include the capability to receive audio from a variety of sources. For example, a hearing assistance device may receive audio from a transmitter or streamer attached to a television (TV). While receiving a streaming transmission, the audio from the hearing assistance device microphone is often attenuated to enhance the listener's experience while streaming audio from a wireless device. However, a hearing impaired person that uses or wears a hearing assistance device can become involved with listening to TV programming or other streamed content and might not hear a doorbell, a fire alarm, burglar alarm, weather alert, carbon monoxide alarm, or other serious alert. Additionally, a spouse, family member or friend might want to talk to the hearing assistance device user while they are watching the TV or otherwise not paying attention. What is needed in the art is an improved system for getting an audible message to a user of a hearing assistance device that the user would otherwise not receive.
Disclosed herein, among other things, are methods and apparatus for providing a gateway for a wireless hearing assistance device.
One aspect of the present subject matter relates to an apparatus, such as a gateway, thr wireless communication with a hearing assistance device. The apparatus includes one or more inputs configured to receive messages and alerts directed to a wearer of a hearing assistance device. A processor is configured to process the messages and alerts to obtain an output adapted to be played via audio to a wearer of the hearing assistance device, and to interrupt a current audio stream being played to the wearer. A wireless transmitter is configured to transmit the output to the hearing assistance device, in various embodiments.
Another aspect of the present subject matter is use in a public multi-cast system. As a wearer of a hearing assistance device comes in the vicinity of a public broadcast service, the streaming audio from the broadcast service can be transmitted via wireless link for reception, in various embodiments.
Another aspect of the present subject matter relates to a method for wirelessly communicating with a hearing assistance device. One or more message and alert inputs are received and the message and alert inputs are processed to obtain an output. The output is wirelessly transmitted to a hearing assistance device, and the output is configured to be played via audio to a wearer of the hearing assistance device and to interrupt a current audio stream being played to the wearer, in various embodiments.
This Summary is an overview of some of the teachings of the present application and not intended to be an exclusive or exhaustive treatment of the present subject matter. Further details about the present subject matter are found in the detailed description and appended claims. The scope of the present invention is defined by the appended claims and their legal equivalents.
The following detailed description of the present subject matter refers to subject matter in the accompanying drawings which show, by way of illustration, specific aspects and embodiments in which the present subject matter may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the present subject matter. References to “an”, “one”, or “various” embodiments in this disclosure are not necessarily to the same embodiment, and such references contemplate more than one embodiment. The following detailed description is demonstrative and not to be taken in a limiting sense. The scope of the present subject matter is defined by the appended claims, along with the full scope of legal equivalents to which such claims are entitled.
The present subject matter relates generally to hearing assistance devices, and in particular to a gateway for a wireless hearing assistance device. The hearing assistance devices referred to herein include, but are not limited to hearing aids. One aspect of the present subject matter relates to an apparatus for wireless communication with a hearing assistance device. The apparatus includes one or more inputs configured to receive messages and alerts directed to a wearer of a hearing assistance device. A processor is configured to process the messages and alerts to obtain an output adapted to be played via audio to a wearer of the hearing assistance device, and to interrupt a current audio stream being played to the wearer. A wireless transmitter is configured to transmit the output to the hearing assistance device, in various embodiments. In still another embodiment the processor within the hearing assistance device itself is programmed to detect and process audio alarms and other audio alerts and under those circumstances can attenuate the wireless audio stream or other acoustic audio input and alert the wearer of an alarm or alert either by amplifying the alert or by playing an audio alert equivalent to the alarm or alert being acoustically played.
A hearing assistance device with wireless communication capability (or wireless hearing assistance device) allows for new services to be offered to the wireless hearing assistance device user, or wearer. The present subject matter provides for alarms, doorbells, audio messages and text messages to be sent to the hearing assistance device user. To enable these services, an entry to the wireless hearing assistance device is required. Currently a TV streamer offers a level of access into the hearing aid for remote control message forwarding. This subject matter allows for other messages, alarms and alerts to be forwarded to the hearing assistance device user. The messages and alerts are collected by a gateway device, in one embodiment. The gateway device is enabled with a wireless link to the hearing assistance device user, in various embodiments. The hearing assistance device user would receive the messages, alerts and alarms over the wireless link. The hearing assistance device would play the audible message, alert or alarm to the hearing assistance device user. In various embodiments, the gateway device has multiple inputs (wired and/or wireless) for alarms, audio input, doorbells, etc. In one embodiment, messages are sent directly to the hearing assistance device from the gateway device. Alternatively, messages can be sent from a gateway device to an accessory device which forwards the message to the hearing assistance device. In an embodiment, messages are sent from a gateway device to a TV streamer device, where they are mixed with the audio stream by a processor (such as a digital signal processor). Messages are sent via CVSD (continuously variable slope delta modulation), G.722, G.726, AAC or other appropriate audio encoding format that can be decoded by the hearing assistance device, in various embodiments.
In various embodiments, accessories such as TV streamers, wireless audio streaming devices, cell phone interfaces, remote controls, gateways and the like can incorporate a microphone input for the purpose of “listening” for alarms. Alarms such as fire, burglar, CO, etc. and alerts such as a doorbell, weather alert, etc. can be activated when a hearing aid wearer is in the process of listening to digital audio inputs from accessory devices which will further impair the user from hearing these household alarms or alerts. In addition, a user would be less likely to hear an incoming telephone call or doorbell when steaming audio via an accessory device. The wireless accessories or dedicated accessory or audio gateway type devices can be equipped with a microphone, in an embodiment. The microphone is used as an input to monitor the ambient acoustic environment to determine if an alarm is sounding. The unit can be put in a training mode before being deployed for use to “learn” the alarm sounds so that each can be distinguished and then unique alerts can be sent to the hearing aid wearer for each alarm, or a generic alert can be sent just to alert the wearer that an alarm is sounding or a phone is ringing. In various embodiments, acoustic inputs being wirelessly forwarded to hearing instruments from accessory devices. Accessory devices may include cell phones or smart phones having wireless communication capability such as 802.11 (WIFI), Bluetooth or other means of wireless communication with a hearing instrument.
It would also be possible to add this feature to hearing aids as well and bypass the accessories. White streaming, the microphone input can still be monitored for critical alarms going off in the acoustic environment, the microphone input can go active and the wireless input can be muted to help aid the patient in hearing the alarm or be alerted to the alarm. Acoustic alarms can also be translated into voice alerts for the hearing instrument wearer, in an embodiment.
A hearing impaired user of a hearing assistance device can become involved with watching TV or other content on a streamer device, and the microphone audio would be attenuated. Both of these factors make it such that the hearing assistance device user might not notice a doorbell, a fire alarm or other serious alert that the hearing assistance device user should be made aware of. Additionally, a spouse, family member or lieind might want to talk to the hearing assistance device user while they are watching the movie or otherwise not readily paying attention. The present subject matter would also allow for a method to enable a conversation with the hearing assistance device user while the person is in a stream.
The subject matter is intended to be able to get an audible message to the hearing assistance device user. The message is sent to the hearing assistance device user via the wireless link such that the signal is amplified and made audible fir the hearing assistance device wearer, in various embodiments. Alternatively, the message can be relayed through a device like a streamer or other accessory, where the message can be mixed with the audio stream.
In various embodiments, a hearing impaired user might have the volume reduced on their assisted listening device, or the assisted listening device might be in a program to attenuate the hearing assistance device. When the alert comes in, the gateway can pass a data message to increase the volume of the assisted listening device to a normal level, thus overriding attenuated volume settings.
Previously, lights have been used to alert hearing impaired users to alarms or alerts. Otherwise loud volume is required to capture the audio link and to get to the hearing assistance device wearer. The previous solutions do not allow for a multitude of alerts/message sources to be funneled to the hearing assistance device user. The present subject matter allows for multiple inputs from the appropriate sources to all be collected, mixed/processed and sent to the hearing assistance device user through wireless transmission. The messages are then played via audio to the user. Using a streamer presents a new scenario where the hearing impaired might not pay attention to his or her surroundings as they might have previously. This subject matter gets the information to the hearing impaired user, promoting safety in the case of alarms or conveying information to the hearing impaired individual so that they get the message.
One embodiment of the present subject matter includes a gateway as a standalone device to receive the inputs and transmit them wirelessly to the hearing assistance device. Alternatively a computer or smart phone can be configured to accept inputs from various sources, and software on the computer can route the message to a wireless dongle or built in wireless device. The signal can then be sent to the hearing assistance device user directly or via a cellular phone/entertainment device (CPED), TV streamer or other device in wireless communication with the hearing assistance device. A CPED is used to send audio streaming or cell phone audio to the hearing assistance device user. The cell phone can also receive messages via SMS services or via Bluetooth® or other wireless interface. When a CPED is used as a gateway, the cell phone can send the message via Bluetooth® to the CPED, where it can be mixed with other audio signals and sent to the hearing assistance device. When a smart phone or cell phone is used as the gateway device, the signals can be sent directly to the hearing instrument via wireless communication such as 802.11, Bluetooth, Bluetooth low energy or other wireless means.
In various embodiments, the present subject matter provides for training the gateway device by placing the device into a learning mode for each audible alarm within the user's home. For example, the gateway device can be placed in “learn fire alarm” mode and then a fire alarm is set off using the test button on the fire alarm device. This alarm is recorded and statistics of the sound would be analyzed by the gateway device so if it heard the alarm again while in normal operation it can forward a voice command to the hearing assistance device, or it can send a fire alarm message to the hearing assistance device where a locally generated alert can be synthesized on the hearing assistance device itself. The learning mode can be used for all other household alarms of telephone rings, burglar alarms, carbon monoxide (CC)) alarms, smoke detectors, weather alerts, etc. Various embodiments provide for automatic detection of fire alarm sounds (using an ANSI standard, for example). In another embodiment the hearing device itself can be trained to analyze such alerts and understand when to mute the stream and play the alarm or alert or an alarm or alert equivalent notification. In various embodiments, the present subject matter is used in a public multi-cast system. As a wearer of a hearing assistance device comes in the vicinity of a public broadcast service, the streaming audio from the broadcast service can be transmitted via wireless link for reception, in various embodiments.
