Sound output. I am using Acer Aspire 5570. I found the sound output (inbuilt) of my laptop

Question

I am using Acer Aspire 5570. I found the sound output (inbuilt) of my laptop relatively low as compared to other laptops. I have checked the general sound systems and have marked highest level for volume but still it is relatively low as compared to others. Is the sound output of Acer Aspire 5570 actually low? If not, what could be the problem and if yes, what can be done to increase it?
