audiometria's Issues

App Definition (incomplete)

The steps below reflect the app flow.

Registration

A initial screen to collect patient's data. Must collect the following:

1. Name
2. Birth date
3. Exam date
4. Sex

Environment noise

A test measuring the noise of the environment must be done to check if the environment is suitable for running the test.

Device used: Hearcheck Screener (Siemens). It stays that the measurement should be less than "50dbNA".

Measurement process

The measurement could have 3 levels:

Green

This indicates that the environment is ideal to perform the test.
The intensity of this level is < 50db

Yellow

This indicates that th test may have some issues.
The intensity of this level is >= 50db and <= 60db

Red

This indicates that the user should not perform the test in this environment.
The intensity of this level is > 60db+

TATP(Triagem auditiva com tons puro)

The measurement process must indicate if the device is playing the sound or not. The device used shows:

• A green
  when playing
• A red
  
  when it's not playing

Frequencies(in this sequence):

The interval between the frequencies must be 4 seconds.

• 1000 Hz
• 2000Hz
• 4000Hz
• 8000Hz
• 500Hz

Intensities

• Starts at 40dBNA(dBNS converted to dBNA).
• Lasts 4 seconds.
• The user informs(a button?) if can hear it.
• If the user CAN hear it, the intensity goes to 20dB, otherwise, goes to 60dB.
• Waits 4 seconds to run it again in the next frequency.
• When the user can't hear it, wait 2 seconds until next amplitude

Results

The results are calculated as follows:

• Result = (Intensity heard of 500Hz measurement + Intensity heard of 500Hz measurement + Intensity heard of 500Hz measurement + Intensity heard of 500Hz measurement ) / 4

Result <= 25dBNA is normal
25dBNA < Result <= 40dBNA = low loss
40dbNA < Result <= 60dBNA = moderate loss
61dBNA < Result <= 80dBNA = severe loss
Result > 80dBNA = profound loss

TASF(Triagem auditiva com sons familiares)

Same process except:
1 - The sounds would be real sounds like claps, dogs, birds, etc, instead of a pure tone.
2 - The would be replaced by a description of the sound.

Considerations

• The sound must be played from 50cm of the patient(approximately length of an arm) in a 0/0 Azimuth position(at the eyes height in front of the nose)
• The intensity cannot be changed by changing the device intensity.
• Possibility to save the result and keep track by name or an id.
• Possibility to send the results by email.
• After their validation, the result could be indicated in a descriptive way like "Your audition is fine" or "You have some hearing loss, you should look for a complete evaluation"

Tutorial

• Ao abrir pela primeira vez avisar que será pedido microfone.
• Explicar que não será coletado dados.
• Ao fim será apresentado um resumo.

Primeira tela/decibelimetro

Assim que o app for iniciado na primeira tela verificar o decibelimetro atualizando a tela entre os 3 estados:

0 - 50 habilita o botao da audiometria e da tom verde na tela
50 - 60 habilita o botao da audiometria e da tom amarelo na tela e avisa sobre a qualidade do teste
60+ - desabilita o botao e da tom vermelho na tela e avisa que o teste nao pode ser realizado devido ao ruido do ambiente.

Tela de audiometria

Deverá mostrar na tela frequência, amplitude, imagem indicando se está tocando som ou não, botao para o usuario indicar se ouviu.
