Made for 0 dB in this example. But I want to diversify it. How to adjust 5dB and 15dB

noisePower = sum(noiseSegment.^2);
cleanPower = sum(audio.^2);
noiseSegment = noiseSegment .* sqrt(cleanPower/noisePower);
noisyAudio = audio + noiseSegment;

db = 10;

noisePower = sum(noiseSegment.^2);

cleanPower = sum(audio.^2);

K = (cleanPower/noisePower)*10^(-dB/10);

noiseSegment = noiseSegment .* sqrt(K); % Change Noise vector

noisyAudio = audio + noiseSegment;

sound(noisyAudio,adsTrainInfo.SampleRate)
