A window can be anything going from zero to unity. In this case it should reach unity after 5ms from the start. You should know what kind of performance you are looking for, so you can determine what response your window should have.

Often I start with 1/4 of a sine period, since it has the nice properties to start with a ramp and that its derivative is continuous when it meets unity. For instance for time array t with begin time b and end time e of the window;

w = ((1+sin(pi*(t-b)/2/e))/2.*(t>b-e)-1 ) .*(t<=b+e)+ 1;

This equals 0 for t<b, then increases and equals 1 for t>e. Also note that Matlab has a large number of windows available.
And note that the way you're implementing the amplitudes is very different form the decibels you specify!

soundsc(y) scales the values of the audio signal y to fit in the range from –1.0 to 1.0, and then sends the data to the speaker at the default sample rate of 8192 hertz. By first scaling the data, soundsc plays the audio as loudly as possible without clipping. The mean of the dynamic range of the data is set to zero.
