Setup

        underscore = window.underscore;
    
    var a = [],
        newArray = [],
        pi = Math.PI;
    
    for (var i = 1, max= 100 ; i <= max ; i++) {
      a.push('Fundamental alert number ' + i);
    }

Test runner

Ready to run.

Testing in
TestOps/sec
jQuery.each
$.each(a, function(index, val) {
  newArray.push(
    val.replace('und', '')
      .replace(/me.*le/, '')
      .replace(/number\s(\d+)/, 'with deciblel level of $1dB')
  );
});
ready
good old for loop
for (var i = 0, len = a.length; i < len; i++) {
  newArray.push(
    a[i].replace('und', '')
      .replace(/me.*le/, '')
      .replace(/number\s(\d+)/, 'with deciblel level of $1dB')
  );
}
ready
underscore.each
underscore.each(a, function(item) {
  newArray.push(
    item.replace('und', '')
      .replace(/me.*le/, '')
      .replace(/number\s(\d+)/, 'with deciblel level of $1dB')
  );
});
ready
Lo-Dash each
lodash.each(a, function(item) {
  newArray.push(
    item.replace('und', '')
      .replace(/me.*le/, '')
      .replace(/number\s(\d+)/, 'with deciblel level of $1dB')
  );
});
ready
array forEach
Array.prototype.forEach.call(a, function(item) {
  newArray.push(
    item.replace('und', '')
      .replace(/me.*le/, '')
      .replace(/number\s(\d+)/, 'with deciblel level of $1dB')
  );
});
