A party in complete silence could be too discomforting for some of your guests. Thus, it is encouraged that you have soft music playing in the background to fill the audio void. This will make many of your guests a little more comfortable. However, don't play the music too loud or some guests will try to use the music as a cover for their whispers. Music should be loud enough to be heard, but not loud enough to cover up any unwelcome talking. Also, music should be instrumental only. Try finding minus tracks to popular songs or just stick to the basics like Chopin and Tchaikovsky.
In order to encourage socializing, guests should wear signs with their cell phone numbers around their necks. This way people can initiate conversation via text. This is great for shy flirts who do not want to be spotted flirting. You can either have your guests put their phones on vibrate or allow ringtones. It is up to you as the host to determine how much silence you would like at your party.
Guests who refuse to comply to the silence rules of this party should be given a silent warning either through a stern look or a text. If guests continue to refuse to be silent, they should be removed from the party. Having a large but silent bouncer would be a good idea.
For any party, it is important to consider food. Some foods, such as pretzels and hard shell tacos, can be quite noisy when eaten. It is best to choose soft foods such as pudding and bananas. However, be careful that the foods you choose do not have noisy wrappers or require utensils that will scrape across plates or bowls. Also, avoid serving carbonated beverages as these tend to fizz when opened.
Some people believe you can't have fun without noise. After this party, they'll be changing the tune (to silence).
