a memory that stores instructions; and
a processor, wherein the processor is configured to execute the instructions to perform operations, the operations comprising:
generating a test signal, wherein the test signal includes multiple frequency components, wherein at least one component lies between the range of 20 Hz and 400 Hz;
sending the test signal to a speaker of an earphone, wherein the earphone includes a first microphone, a second microphone, the speaker, wherein the earphone is configured to accept a sealing section and wherein the sealing section is configured to form an acoustic barrier between a first side of the earphone and a second side of the earphone when the earphone is worn by a user;
receiving a first microphone signal from the first microphone;
calculating a value, using a first signal and a second signal, wherein the value is the result of a non phase calculation of at least one of a coherence, or a correlation, or a cross-correlation, or a difference, or a combination thereof, wherein the second signal can be at least one of the test signal or a reference response or a combination thereof;
determining a seal of the earphone by comparing the value to a threshold to determine a seal quality between the first side and the second side, wherein a seal quality can have one or more values, wherein a value can be at least one of numerical or a word or a phrase or a combination thereof;
generating a message to convey the seal quality, wherein the message can include at least one of the words “good”, or “bad”, or “fair”, or “poor”, a combination thereof, or a synonym of at least one of the words; and
