Techniques for increasing processing capability in hear aids

A hearing aid, comprising:

• a microphone to convert an audio input into an input signal;
• processing circuitry to process the input signal to produce an output signal in a manner that compensates for a user's hearing deficit;
• a speaker to convert the output signal into an audio output;
• wherein the processing circuitry is configured to select from two or more processing algorithms that differ in delay time to produce the output signal and to select the processing algorithm according to an estimated signal-to-noise ratio (SNR) of the audio signal received by the microphone;
• and,
• wherein the processing circuitry is configured to select a processing algorithm with a delay of 10 milliseconds or less when the SNR is greater than +5 dB.
