Emergency Vehicle Audio Synchronization
An example system for a synchronizing audio on emergency vehicles can include a receiver configured to accept a synchronization signal. The example system can also include a processor configured to use the synchronization signal to determine a correct playback time for a message to remain in sync with other emergency vehicles.
1 . A system for a synchronizing audio on emergency vehicles, comprising:
a receiver configured to accept a synchronization signal; and
a processor configured to use the synchronization signal to determine a correct playback time for a message to remain in sync with other emergency vehicles.
2 . The system of claim 1 , further comprising high and low frequency speakers and amplifiers that cover a wide range of audible frequencies, with the high and low frequency speakers being configured to playback the message.
3 . The system of claim 2 , further comprising a radio receiver capable of receiving an audio signal with the message from a nearby emergency vehicle and playing the message over the high and low frequency speakers.
4 . The system of claim 3 , further comprising a graphical user interface that allows new audio messages to be transferred to the system.
5 . The system of claim 1 , further comprising a remote computing device, wherein the remote computing device has a microphone that allows for recording of the message and transfer of the message directly to a plurality of the other emergency vehicles.
6 . The system of claim 1 , wherein the message is a series of tones or prerecorded.
7 . The system of claim 1 , further comprising an outdoor warning speaker, wherein the message is synchronized with the outdoor warning speaker.
8 . The system of claim 1 , wherein the processor defines a common time base as part of the synchronization signal.
9 . The system of claim 1 , wherein the processor defines a zone for the emergency vehicles, and wherein another emergency vehicle entering the zone will receive the synchronization signal and playback the message.
10 . The system of claim 9 , wherein a first vehicle of the emergency vehicles to playback the message becomes a synchronizer, and wherein other of the emergency vehicles synchronize playback of the message with the first vehicle.
11 . A method for a synchronizing audio on emergency vehicles, comprising:
accepting a synchronization signal; and
using the synchronization signal to determine a correct playback time for a message to remain in sync with other emergency vehicles.
12 . The method of claim 11 , further comprising high and low frequency speakers and amplifiers that cover a wide range of audible frequencies, with the high and low frequency speakers being configured to playback the message.
13 . The method of claim 12 , further comprising receiving an audio signal with the message from a nearby emergency vehicle and playing the message over the high and low frequency speakers.
14 . The method of claim 13 , further comprising a graphical user interface that allows new audio messages to be transferred.
15 . The method of claim 11 , further comprising a remote computing device, wherein the remote computing device has a microphone that allows for recording of the message and transfer of the message directly to a plurality of the other emergency vehicles.
16 . The method of claim 11 , wherein the message is a series of tones.
17 . The method of claim 11 , wherein the message is prerecorded or custom.
18 . The method of claim 11 , further comprising defining a common time base as part of the synchronization signal.
19 . The method of claim 11 , further comprising:
defining a zone for the emergency vehicles; and
when another emergency vehicle enters the zone, receiving the synchronization signal for playback of the message.
20 . The method of claim 19 , wherein a first vehicle of the emergency vehicles to playback the message becomes a synchronizer, and wherein other of the emergency vehicles synchronize playback of the message with the first vehicle.
