Sound pressure level monitoring and notification system
View Patent ↗Methods of acoustic dose monitoring and acoustic dose systems are provided. An acoustic dose system includes a first device configured to measure sound pressure levels directed to an ear drum and a second device configured to convert the sound pressure levels into a sound pressure level dose. The second device sends a notification signal to a third device if the sound pressure level dose is larger than a threshold value.
1. An acoustic dose system comprising:
a first device configured to measure sound pressure levels directed to an ear drum; and
a second device configured to convert the sound pressure levels into a sound pressure level dose, where the second device selects an audio content from a list of audio content when the sound pressure level dose is larger than a first threshold value, the audio content being selected such that a combination of the sound pressure level dose and a dose of the audio content is less than a second threshold value, the selected audio content being sent to a third device.
2. The system according to claim 1 , where the third device is a computer system.
3. The system according to claim 1 , where the third device is an audio playback device.
4. The system according to claim 1 , where the third device is a communication device.
5. The system according to claim 1 , where the first threshold value is 80% of a daily sound pressure level dose or a daily noise dose.
6. The system according to claim 1 , further comprising:
a coupling between the second and third devices such that the second device receives a monitoring signal from the third device.
7. The system according to claim 6 , where the monitoring signal is used by the second device to control at least a portion of the sound pressure levels directed to the ear drum.
8. A method of acoustic dose monitoring comprising:
monitoring sound pressure levels directed to an ear drum by a first device;
calculating a sound pressure level dose from the monitored sound pressure levels by a second device;
comparing, by the second device, the sound pressure level dose with a first threshold value; and
selecting, by the second device, an audio content from a list of audio content when the sound pressure level dose is greater than the first threshold value, the audio content being selected such that a combination of the sound pressure level dose and a dose of the audio content is less than a second threshold value, the selected audio content being sent to a third device.
9. The method according to claim 8 further comprising:
receiving a monitoring signal from the third device, where the monitoring signal is used by the second device to control at least a portion of the sound pressure levels directed to the ear drum.
10. The method according to claim 9 , where the portion of the sound pressure level directed to the ear drum is due to an acoustic signal emitted by a receiver.
