Which hearing protectors are best for construction workers?

While there is an array of activities happening on a work site at any given time, most construction noise averages less than 100 dB, ranging between 85 - 95 dB.

Answer Extra: 

While this does not lessen the need for hearing protective devices (HPDs), using lower attenuating and uniform attenuating hearing protectors can help workers avoid overprotection and thus improve overall worker safety.
