Occlusion device capable of occluding an ear canal

1. A device for occluding an ear canal, comprising:

a first microphone;

a second microphone;

a speaker;

memory that stores instructions;

a pump;

an occlusion section, where the occlusion section comprises:

an insertion element;

an acoustic channel, where the speaker is configured to deliver audio content through the acoustic channel; and

an expandable element disposed on the insertion element, wherein the expandable element encompasses a cavity;

a processor that executes the instruction to perform operations, the operations comprising:

receiving a command to pump a medium into a cavity formed by expandable element, wherein the pumping is stopped when the medium added exceeds a predetermined amount, wherein the predetermined amount is selected so that an attenuation across the expandable element decreases with increasing frequency above 400 Hz.

2. The device of claim 1 , further comprising a housing unit including an inflation management system for controlling transfer of the medium.

3. The device of claim 2 , wherein the housing unit further comprises a user interface coupled to the inflation management system, wherein the inflation management system is configured to be activated using the user interface.

4. The device of claim 3 , wherein, upon activation via the user interface, the inflation management system is configured to pump medium into the expandable element.

5. The device of claim 2 , further comprising a housing unit including, a controller, a memory, a battery, a communication unit, or a combination thereof.

6. The device of claim 1 , further including:

a memory that stores instructions.

7. The device of claim 6 , wherein the processor is operatively coupled to the memory, wherein the processor executes the instructions to perform operations comprising:

sending an audio signal to the speaker;

receiving a microphone signal from the first microphone; and

analyzing the microphone signal to determine a seal integrity.

8. The device according to claim 6 , wherein the processor is operatively coupled to the memory, wherein the processor executes the instructions to perform operations comprising:

receiving a microphone signal from the first microphone, wherein the first microphone measures the ambient sound level;

receiving an audio signal;

receiving a user indicated ratio of an audio signal sound level to the ambient sound level; and

generating a modified signal by mixing the audio signal with the microphone signal.

9. The device of claim 1 , wherein the expandable element comprises a plurality of layers including an inner non-foam layer, an outer foam layer for contact with the ear canal, or a combination thereof.

10. The device of claim 1 , wherein the first microphone is an ear canal microphone configured to measure a sound pressure level in the ear canal.

11. The device of claim 1 , wherein the processor is operatively coupled to the memory, wherein the processor executes the instructions to perform operations comprising:

sending an audio signal to the speaker;

receiving a microphone signal from the second microphone; and

analyzing the microphone signal to determine a seal integrity.

12. A device for occluding an ear canal, comprising:

a first microphone;

a second microphone;

a speaker;

a processor; and

an occlusion section, where the occlusion section comprises:

an insertion element;

an acoustic channel, where the speaker is configured to deliver audio content through the acoustic channel; and

an expandable element disposed on the insertion element forming a cavity about the insertion element, wherein the expandable element expands upon receiving a medium into the cavity and provides a transmission loss that decreases with increasing frequency after 400 Hz,

wherein the expandable element is configured to form an acoustic seal with a portion of an ear canal wall of an ear canal.
